# 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
