Badge Polish: Gear Animation + Custom Color Picker — Implementation Plan

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: Animate the gear icon reveal on badge hover and replace all native <input type="color"> elements with a tabbed inline color picker (Palette, Named Colors, Custom HSV).

Architecture: The gear animation is a CSS-only change (2 lines). The custom color picker is a new vanilla JS module (color-picker.js) that builds a tabbed widget with three panels: a Tailwind/shadcn palette grid, CSS named colors grid, and an HSV picker with canvas-rendered SV square + hue bar. The module exposes a create() factory that returns a picker instance with open/close/setColor/isOpen/destroy methods and an .el property for DOM insertion. The picker is integrated into the inline popover (color-popover.js) and the extension popup (popup.js).

Tech Stack: Vanilla JS, HTML5 Canvas, CSS, Firefox WebExtension APIs (manifest v2).

Global Constraints

• No external dependencies — vanilla JS only, no build step
• Must work in both Firefox content script and popup contexts
• Colors stored as lowercase #rrggbb hex strings
• All CSS classes prefixed with rt- to avoid conflicts with Reddit's styles
• Dark mode support via .rt-dark class on ancestor elements
• Spec: docs/superpowers/specs/2026-08-26-badge-polish-design.md

Task 1: Gear Icon Animation

Files:

• Modify: content/styles/badges.css:32-38

Interfaces:

• Consumes: nothing

• Produces: nothing (CSS-only, no API changes)

• Step 1: Update .rt-badge--subreddit and add hover rule

In content/styles/badges.css, replace the .rt-badge--subreddit block:

.rt-badge--subreddit {
  position: relative;
  padding-right: 18px;
  background: var(--rt-sub-bg, #fde8e0);
  border-color: var(--rt-sub-border, #c84a20);
  color: var(--rt-sub-text, #c84a20);
}

with:

.rt-badge--subreddit {
  position: relative;
  padding-right: 6px;
  transition: padding-right 0.15s;
  background: var(--rt-sub-bg, #fde8e0);
  border-color: var(--rt-sub-border, #c84a20);
  color: var(--rt-sub-text, #c84a20);
}

.rt-badge--subreddit:hover {
  padding-right: 18px;
}

• Step 2: Verify manually

Load old.reddit.com with the extension enabled. Verify:

1. Subreddit badges have no gap at rest (padding matches left side).
2. Hovering over a subreddit badge smoothly expands it to reveal the gear icon (~150ms).
3. The adjacent comments badge shifts right during expansion.
4. On mouse-out, the badge shrinks and the gear fades out.

• Step 3: Commit

git add content/styles/badges.css
git commit -m "feat: animate gear icon reveal on badge hover"

---

Task 2: Color Picker Widget + CSS

Files:

• Create: content/tweaks/color-picker.js
• Modify: content/styles/badges.css (append picker CSS at end)
• Modify: popup/popup.css (append picker CSS at end)
• Modify: manifest.json:20-25

Interfaces:

• Consumes: nothing

• Produces: window.RedditTweaks.colorPicker with:

  • create() → returns { el: HTMLElement, open(hex, onChange), close(), setColor(hex), isOpen(), destroy() }

• Step 1: Create content/tweaks/color-picker.js

}

• Step 3: Append picker CSS to popup/popup.css

Add the same picker CSS block from Step 2 at the end of popup/popup.css. The dark mode rules won't apply in the popup (no .rt-dark ancestor) but are harmless.

• Step 4: Update manifest.json

Add content/tweaks/color-picker.js to the content scripts JS array, before color-popover.js (the popover depends on the picker):

"js": [
  "lib/settings.js",
  "content/tweaks/badges.js",
  "content/tweaks/color-picker.js",
  "content/tweaks/color-popover.js",
  "content/main.js"
]

• Step 5: Verify manually

Load old.reddit.com, open the browser console, and verify:

1. window.RedditTweaks.colorPicker exists and has a create method.
2. var p = window.RedditTweaks.colorPicker.create(); returns an object with el, open, close, setColor, isOpen, destroy.
3. document.body.appendChild(p.el); p.open("#ff0000", function(h){ console.log(h); }); shows the picker with three tabs.
4. Clicking palette swatches logs hex values.
5. Clicking named color swatches logs hex values.
6. Dragging on the Custom tab's SV square/hue bar logs hex values.
7. Clean up: p.destroy();

• Step 6: Commit

git add content/tweaks/color-picker.js content/styles/badges.css popup/popup.css manifest.json
git commit -m "feat: add tabbed color picker widget (palette, named colors, custom HSV)"

---

Task 3: Popover Integration

Files:

• Modify: content/tweaks/color-popover.js
• Modify: content/styles/badges.css:180-187 (update swatch selector)

Interfaces:

• Consumes: window.RedditTweaks.colorPicker.create() → { el, open, close, setColor, isOpen, destroy }

• Produces: Updated popover using custom picker instead of native <input type="color">

• Step 1: Update swatch CSS selector in badges.css

Replace the selector for the native color input:

.rt-popover-row input[type="color"] {
  width: 28px;
  height: 20px;
  border: 1px solid #ccc;
  border-radius: 3px;
  padding: 1px;
  cursor: pointer;
}

with:

.rt-popover-row .rt-color-swatch {
  width: 28px;
  height: 20px;
  border: 1px solid #ccc;
  border-radius: 3px;
  cursor: pointer;
  display: inline-block;
  vertical-align: middle;
}

Also replace the dark mode variant:

.rt-color-popover.rt-dark .rt-popover-row input[type="color"] {
  border-color: #555;
}

with:

.rt-color-popover.rt-dark .rt-popover-row .rt-color-swatch {
  border-color: #555;
}

• Step 2: Rewrite color-popover.js

Replace the entire file with the updated version. Key changes from the previous version:

• <input type="color"> → <div class="rt-color-swatch"> in the HTML template
• Add var picker = null; and var activeProp = null; at module scope
• Create picker lazily in createPopover() and insert between body and preview
• Swatch input event → click handler that opens/toggles picker
• Hex input handler syncs picker via picker.setColor() when open
• loadModeIntoInputs() sets swatch.style.backgroundColor instead of .value
• updatePreview() and storeCurrentEdits() read from hex.value instead of swatch.value
• Mode toggle closes picker
• close() closes picker and resets activeProp
• onDocumentMouseDown excludes clicks inside picker.el
• Remove the active.type === "color" check (no longer relevant)

Full replacement content for content/tweaks/color-popover.js:

  "use strict";

  window.RedditTweaks = window.RedditTweaks || {};
  window.RedditTweaks.colorPopover = {
    open: open,
    close: close,
    refreshTheme: refreshTheme,
  };
})();

• Step 3: Verify manually

Load old.reddit.com. Open the inline color popover by hovering a subreddit badge and clicking the gear. Verify:

1. Color rows show swatch divs (colored rectangles) instead of native color pickers.
2. Clicking a swatch opens the tabbed picker below the rows.
3. Palette tab: clicking a Tailwind swatch updates the row's swatch + hex input + preview badge.
4. Named tab: clicking a named color works the same.
5. Custom tab: dragging the SV square and hue bar updates live.
6. Clicking the same swatch toggles the picker closed.
7. Clicking a different swatch switches the picker to that property.
8. Typing a valid hex updates the picker's state.
9. Mode toggle closes the picker and loads the other mode's colors.
10. Cancel/Escape/click-outside dismisses the popover cleanly.
11. Save persists the colors.
12. Dark mode styling works (if RES night mode is available).

Task 4: Popup Integration

Files:

• Modify: popup/popup.html:72-73
• Modify: popup/popup.js
• Modify: popup/popup.css:85-92

Interfaces:

• Consumes: window.RedditTweaks.colorPicker.create() → { el, open, close, setColor, isOpen, destroy }

• Produces: Updated popup with custom picker for all global and per-subreddit color controls

• Step 1: Add script tag to popup.html

Add the color-picker script before popup.js:

  <script src="../lib/settings.js"></script>
  <script src="../content/tweaks/color-picker.js"></script>
  <script src="popup.js"></script>

• Step 2: Replace <input type="color"> with swatch divs in popup.html

Replace all 12 <input type="color" ...> elements with <div> elements. Each keeps its id attribute.

Light Mode Colors section:

    <div class="section">
      <h2>Light Mode Colors</h2>
      <fieldset>
        <legend>Subreddit Badge</legend>
        <label>Background <div class="rt-color-swatch" id="light.subredditBgColor"></div></label>
        <label>Border <div class="rt-color-swatch" id="light.subredditBorderColor"></div></label>
        <label>Text <div class="rt-color-swatch" id="light.subredditTextColor"></div></label>
      </fieldset>
      <fieldset>
        <legend>Comments Badge</legend>
        <label>Background <div class="rt-color-swatch" id="light.commentsBgColor"></div></label>
        <label>Border <div class="rt-color-swatch" id="light.commentsBorderColor"></div></label>
        <label>Text <div class="rt-color-swatch" id="light.commentsTextColor"></div></label>
      </fieldset>
      <button id="resetLight" class="btn-secondary">Reset Light Defaults</button>
    </div>

Dark Mode Colors section:

    <div class="section">
      <h2>Dark Mode Colors</h2>
      <fieldset>
        <legend>Subreddit Badge</legend>
        <label>Background <div class="rt-color-swatch" id="dark.subredditBgColor"></div></label>
        <label>Border <div class="rt-color-swatch" id="dark.subredditBorderColor"></div></label>
        <label>Text <div class="rt-color-swatch" id="dark.subredditTextColor"></div></label>
      </fieldset>
      <fieldset>
        <legend>Comments Badge</legend>
        <label>Background <div class="rt-color-swatch" id="dark.commentsBgColor"></div></label>
        <label>Border <div class="rt-color-swatch" id="dark.commentsBorderColor"></div></label>
        <label>Text <div class="rt-color-swatch" id="dark.commentsTextColor"></div></label>
      </fieldset>
      <button id="resetDark" class="btn-secondary">Reset Dark Defaults</button>
    </div>

• Step 3: Update swatch CSS selector in popup.css

Replace:

fieldset input[type="color"] {
  width: 40px;
  height: 24px;
  border: 1px solid #ccc;
  border-radius: 3px;
  padding: 1px;
  cursor: pointer;
}

with:

fieldset .rt-color-swatch {
  width: 40px;
  height: 24px;
  border: 1px solid #ccc;
  border-radius: 3px;
  cursor: pointer;
  display: inline-block;
  vertical-align: middle;
}

• Step 4: Rewrite popup.js

Replace the entire file. Key changes from the previous version:

• Add getColorValue(el) / setColorValue(el, val) helpers for reading/writing swatch div values
• Create a shared picker instance
• Wire swatch click handlers for global colors in init()
• Replace el.value reads/writes with helper calls for color elements
• Replace <input type="color"> creation in addSubredditEntry() with swatch divs
• Replace el.addEventListener("input", saveFromControls) for color elements with picker-based flow

Full replacement content for popup/popup.js:

• Step 5: Add swatch styles for subreddit entries to popup.css

The subreddit entry swatches need sizing. Add after the .subreddit-entry-colors block:

.subreddit-entry-colors .rt-color-swatch {
  width: 40px;
  height: 24px;
  border: 1px solid #ccc;
  border-radius: 3px;
  cursor: pointer;
}

• Step 6: Verify manually

Open the extension popup (click the toolbar icon). Verify:

1. All global color controls show swatch divs (colored rectangles) instead of native color pickers.
2. Clicking a global swatch opens the tabbed picker below it.
3. All three tabs work: Palette, Named Colors, Custom.
4. Selecting a color updates the swatch and saves settings.
5. Per-subreddit entries also use swatch divs.
6. Clicking a per-subreddit swatch opens the picker.
7. Mode toggle in per-subreddit entries closes any open picker.
8. Adding a new subreddit entry closes any open picker.
9. Reset buttons work and close any open picker.
10. Only one picker is open at a time across all swatches.

• Step 7: Commit

git add popup/popup.html popup/popup.js popup/popup.css
git commit -m "feat: integrate tabbed color picker into extension popup"
