# Player Controls Polish — Round 2

**Date:** 2026-09-23 07:56 UTC  
**Task:** Five UI polish changes to the floating PlayerControls panel

## Changes Made

All changes in `src/lib/components/PlayerControls.svelte`.

### 1. Enlarged center playback icons by 50%
- Play/Pause: 27 -> 40
- Rewind/FastForward: 24 -> 36
- `.ctrl-btn.play-btn` min-width: 48px -> 64px

### 2. Reorganized Cut Clip buttons into center group
- Moved the "cut at playhead" Scissors button from the right settings group into the center playback group, placed after FastForward. Icon enlarged to 36 to match.
- Added a new "cut before" Scissors button to the left of Rewind. It is hidden by default (`width: 0; opacity: 0; pointer-events: none`) and reveals on `.controls-group.center:hover` with a smooth transition. Appears at 0.7 opacity, full opacity on direct hover.
- Removed the old Scissors button and its right-click handler from the right group.
- New center group order: [Cut-before (hidden)] [Rewind] [Play/Pause] [FastForward] [Cut-at]

### 3. Narrowed floating panel by ~15%
- Overlay insets changed from `left: 15%; right: 15%` (70% width) to `left: 20%; right: 20%` (60% width).

### 4. Restyled volume slider to match seek bar
- Replaced native `accent-color` styling with `appearance: none` custom CSS.
- Track uses transparent background with JS-driven `linear-gradient` inline style showing accent color for the filled portion and `rgba(255,255,255,0.2)` for the dormant portion.
- Thumb is a 10px circle matching seek bar thumb, hidden by default and shown on hover.
- Added `volumePercent` derived state to compute the gradient stop value.

### 5. Replaced slide animation with pure fade
- Removed `transform: translateY(6px)` from `.panel-content` and its `translateY(0)` visible state.
- Changed transition to `opacity 0.35s ease` only (was `opacity 0.2s ease, transform 0.2s ease`).
- Blur `::before` pseudo-element now fades with `opacity 0.35s ease` instead of instant `visibility` toggle. Uses `visibility 0s 0.35s` delay on hide and `visibility 0s 0s` on show to keep pointer-events correct while avoiding the flash.

## Verification
- `svelte-check`: 0 errors, 0 warnings
- `vitest run`: 69 tests passed across 10 test files

## Lessons Learned
- WebKit's `backdrop-filter` still renders correctly with `opacity` transitions as long as the blur layer itself isn't being destroyed/recreated. The `visibility` + delayed `transition` pattern keeps the composited blur layer alive during fade.
- Using `linear-gradient` as an inline style on range inputs is the cleanest way to show a filled/unfilled track without shadow DOM hacks, since WebKit's `::-webkit-slider-runnable-track` doesn't support `background` in scoped Svelte styles as reliably.

## Follow-up Items
- None identified. Visual QA recommended to confirm feel of 0.35s fade timing and hidden cut-before button hover UX.
feat: v0.2.1 — Player controls polish, screenshot capture, quit shortcut v0.2.0 introduced Player mode with floating controls, auto-hide UI, PiP, fullscreen, JKL shuttle, speed selector, captions, and cut-clip. v0.2.1 builds on that with extensive UI polish and new features: Player Controls Polish: - Enlarged center playback icons (Play 48, Rewind/FF 36) with filled SVGs - Moved Cut Clip scissors into center group with hidden cut-before button - Narrowed floating panel from 70% to 60% width - Custom-styled volume slider matching seek bar (linear-gradient fill) - Pure opacity fade animation (0.35s) replacing slide-in - Tinted panel background (rgba(53,54,80,0.75)) visible on black canvas - Drop shadow on center transport controls - Scissors buttons dimmed via color (not opacity) with single-property transitions - ScissorsLineDashed icon for cut-before variant - Timestamps in single seek row (time \| bar \| duration) with sans-serif font - Milliseconds shown at smaller size, revealed on hover Screenshot Capture (S / Shift+S): - Canvas compositing at native video resolution with optional caption burn-in - Caption rendering matches CSS preview (font, background, outline, word highlight) - New Rust save_screenshot command using existing filename pattern - Output: {title} - {ms}ms-screenshot.png - crossorigin=anonymous on video element for untainted canvas Other: - Q keyboard shortcut to quit via Tauri process plugin - formatTimeParts() utility for split timestamp rendering - Updated About dialog shortcuts list - Version bump to 0.2.1 Co-authored-by: Cursor <cursoragent@cursor.com> 2026-09-23 05:30:45 -04:00			`# Player Controls Polish — Round 2`
