# Laputa App Redesign — Implementation Plan

> Generated from `ui-design.pen` (V2) vs current implementation. **Analysis only — do not implement yet.**

---

## Summary of Changes

The V2 design introduces: a **Status Bar**, **Tab Bar** in the editor, an **Info Bar** (breadcrumb + actions), restructured **Sidebar** with Phosphor icons and collapsible groups with count badges, **IBM Plex Mono** for type pills, updated **color palette** (new primary `#155DFF`, new accent colors), and several layout/spacing refinements throughout.

### 8. Icon Library Change
**Current**: Lucide React throughout
**New**: **SF Symbols** (Apple's native icon set) for all new/redesigned icons. Use `sf-symbols-react` or inline SVGs extracted from SF Symbols app.

**Note**: The Pencil design used Phosphor as a placeholder — Luca's intent is SF Symbols throughout. Map Phosphor names to SF Symbol equivalents:
- `magnifying-glass` → `magnifyingglass`
- `star` → `star.fill`
- `folder-open` → `folder`
- `flask` → `flask`
- `target` → `target`
- `arrows-clockwise` → `arrow.clockwise`
- `users` → `person.2`
- `calendar-blank` → `calendar`
- `tag` → `tag`
- `plus` → `plus`
- `columns` → `rectangle.split.2x1`
- `arrows-out-simple` → `arrow.up.left.and.arrow.down.right`
- `sliders-horizontal` → `slider.horizontal.3`
- `cursor-text` → `character.cursor.ibeam`
- `sparkle` → `sparkles`
- `dots-three` → `ellipsis`
- `git-branch` → `arrow.triangle.branch`
- `gear` → `gearshape`

**Action**: Find the best approach for SF Symbols in React/Tauri (e.g., `sf-symbols-react`, SVG extraction, or native font)

## Implementation Phases

### Phase 1: Theme & Typography Updates
**Scope**: CSS variables, fonts, colors — no structural changes
**Files**: `src/index.css`, `index.html` (or font import)
**Estimated effort**: 1 Claude Code session

1. **Add IBM Plex Mono font** — add Google Fonts import or npm package
2. **Update color variables in `index.css`**:
   - `:root` (light): `--primary: #155DFF`, `--accent-green: #00B38B`, `--accent-purple: #A932FF`, `--accent-blue: #155DFF`
   - `.dark`: same primary `#155DFF`, accent-green `#00B38B`, accent-purple `#A932FF`
   - Add new variables: `--accent-yellow`, `--accent-blue-light`, `--accent-green-light`, `--accent-purple-light`, `--accent-red-light`, `--accent-yellow-light` (both modes)
   - Update all `--ring`, `--sidebar-primary`, `--sidebar-ring` to match new primary
   - Update app-specific vars: `--accent-blue`, `--accent-green`, `--accent-purple`, `--accent-blue-bg` etc.
3. **Update `theme.json`**:
   - `headings.h2.fontSize`: 27 → 24
   - `editor.paddingHorizontal`: 40 → 64
   - `editor.paddingVertical`: 20 → 32
4. **Install Phosphor Icons**: `pnpm add @phosphor-icons/react`

### Phase 2: Sidebar Restructure
**Scope**: Sidebar layout, navigation, icons
**Files**: `src/components/Sidebar.tsx`
**Estimated effort**: 1 Claude Code session

1. **Header**: Replace theme toggle with search icon (Phosphor `MagnifyingGlass`) + gear icon. Move theme toggle to status bar settings or a menu.
2. **Add search input** below header: Phosphor magnifying-glass prefix, 13px, bg `--secondary`, border-radius 6px
3. **Top nav**: Reduce to "All Notes" (Phosphor `FileText` 16px) and "Favorites" (Phosphor `Star` 16px), each with count badge pill
4. **Section groups**: Restructure to new pattern with:
   - Consistent chevron + Phosphor icon (18px, bold) + label (13px/600) + count badge
   - Icons: `FolderOpen` (Projects), `Flask` (Experiments), `Target` (Responsibilities), `ArrowsClockwise` (Procedures), `Users` (People), `CalendarBlank` (Events), `Tag` (Topics)
   - Move People and Events from filters to section groups
   - Remove "Untagged", "Changes", "Trash" from nav
5. **Commit button**: Update styling to match design (padding, badge style)
6. **Remove** People/Events/Changes/Trash/Untagged filter items

### Phase 3: NoteList Updates
**Scope**: Header, type pills, note item styling
**Files**: `src/components/NoteList.tsx`
**Estimated effort**: 1 Claude Code session

1. **Header**: Replace badge + create button with search icon (Phosphor `MagnifyingGlass`) + plus icon (Phosphor `Plus`), gap 12px
2. **Remove or hide** the always-visible search input — add toggle behavior on search icon click
3. **Type pills**: Switch to IBM Plex Mono, ALL CAPS format ("ALL 24", "PROJECTS 4"), update active/inactive styles per design
4. **Selected note**: Update to `bg: #2383E212`, left accent 3px `#2383E2` (update to new primary), remove type badge and status text from items
5. **Note items**: Adjust padding to 10px 16px, snippet line-height 1.5, remove type/status badges from individual items

### Phase 4: Editor — Tab Bar & Info Bar
**Scope**: New sub-components within Editor
**Files**: `src/components/Editor.tsx`, `src/components/Editor.css`
**Estimated effort**: 1 Claude Code session

1. **Tab Bar** (top of editor):
   - 45px, bg `--sidebar`, border-bottom
   - Active tab: bg `--background`, border-right, 12px/500 text, X close button
   - Inactive tab: muted text, hidden X (show on hover)
   - Right controls: Plus + Split (disabled) + Expand (disabled) — Phosphor icons
2. **Info Bar** (below tab bar):
   - 45px, bg `--background`, border-bottom
   - Left: breadcrumb `Type › Title · N words · M` (M in accent-yellow when modified)
   - Right: icon buttons (magnifying-glass functional, git-branch/cursor-text/sparkle/dots-three as **disabled placeholders** with `opacity: 0.4, cursor: not-allowed`)
3. **Adjust editor content padding** to 32px 64px per design

### Phase 5: Status Bar + Inspector Polish
**Scope**: New StatusBar component, Inspector refinements
**Files**: New `src/components/StatusBar.tsx`, `App.tsx`, `App.css`, `src/components/Inspector.tsx`
**Estimated effort**: 1 Claude Code session

1. **StatusBar.tsx** (new component):
   - 30px fixed at bottom, bg `--sidebar`, border-top 1px
   - Left: version + branch + sync status
   - Right: AI model + notes count + bell (disabled placeholder) + settings (disabled placeholder)
   - All Lucide icons 13-14px
2. **App.tsx / App.css**: Add StatusBar below main content, wrap layout in vertical flex (main panels + status bar)
3. **Inspector refinements**:
   - Header: Phosphor `SlidersHorizontal` icon + "Properties" label + Phosphor `X` close
   - Status badge: use `--accent-*-light` bg colors with `--accent-*` text
   - "+ Add property" and "+ Link existing" buttons: match border/radius/padding from design
   - History items: left-border 2px timeline style, 10px date text

### Phase 6: Icon Migration & Cleanup
**Scope**: Replace Lucide icons with Phosphor where specified
**Files**: All components
**Estimated effort**: 1 Claude Code session

1. **Audit all icon usage** across components
2. **Replace with Phosphor** where the design specifies (sidebar nav, section icons, NoteList header, editor toolbar icons, inspector)
3. **Keep Lucide** for: chevrons, X/close, tab close, status bar icons, git-commit-horizontal
4. **Remove unused Lucide imports**
5. **Visual verification**: Run `pnpm dev` and compare with `ui-design-screenshot.png`
