v0.1.3 Polish/Tweaks Implementation Summary

Date: 2026-09-22 16:55 ET Version: 0.1.2 → 0.1.3

Task Description

Implemented three UI polish features for v0.1.3 of the GUI Video Clipper (Tauri + Svelte 5):

1. Adjustable clip list layout — clip list can appear below the timeline (default) or as a left sidebar next to the video preview, with a toolbar toggle button and persisted preference
2. Timeline timestamp magnification — increased base font from 10px to 12px, with a mouse-proximity magnification effect using cosine interpolation (~18px peak, 80px radius)
3. Timeline right-click context menu — custom context menu replacing the default web menu, with Mark In/Out, Go to Clip Start/End, and Delete Clip actions

Process

Used subagent-driven development: 5 tasks dispatched as subagents with task reviews between each. Two reviewer findings on Task 2 (falsy width check, narrow-window clamp) were fixed before proceeding.

Lessons Learned

• The layout restructure required careful conditional rendering in App.svelte — the {#if}/{:else} approach creates two separate DOM trees. This means TransportControls gets remounted on layout toggle, which should be smoke-tested.
• Context menu $effect for viewport clamping can flash position (0,0) for one frame before adjustment — initializing adjusted positions from the raw x/y props would eliminate this.
• The bump-version.sh script doesn't sync package-lock.json — needed manual npm install --package-lock-only.

Follow-Up Items

• Manual smoke test with npm run tauri dev — layout toggle, sidebar resize, timestamp magnification feel, context menu flow
• Consider fixing first-frame context menu position flash
• Consider adding onresize clamp for sidebar width when window shrinks below saved width
