## v2.0

*Settings panel overhaul and UI polish*

### Settings Panel — Layout

- Rebuilt the entire settings panel layout from scratch using a shared column grid
- All sections (Gates, Gate Colours) now share the same column positions — headers align top-to-bottom across sections
- All content has equal left and right padding — right edges of every row are flush across the full panel
- Panel width reduced from 560px to 490px, auto-fit to content
- Removed dark background bands from sub-section headers — cleaner, lighter appearance
- Panel height auto-calculated from content cursor position

### Settings Panel — Gate Overlay Section

- Added **X/Y position boxes** showing the current overlay offset — always populated on login from saved data, no longer blank until first move
- Added **Set button** — type X/Y values directly and apply them
- Added **Center H** and **Center V** buttons — snap overlay to horizontal or vertical screen centre independently
- Added **x1 label** restored to nudge row; nudge buttons aligned with position boxes above
- **Reset** button moved from the position row to the end of the nudge row
- All overlay section content uses the available panel width with consistent spacing

### Settings Panel — Gate Colours Section

- Colour swatches are now 1:1 squares (22×22px) matching button height
- R/G/B column positions aligned with X/Y/SetP columns in the Gates section

### Settings Panel — Gates Section

- Gate colour swatches span full row block height and align flush with name boxes

### ElvUI Colour Hook

- Text colours are now derived from the ElvUI theme at login
  - `textHi` (section titles) scales with backdrop brightness
  - `textMid` (row labels) scales with backdrop brightness
  - `textDim` (column headers) scales with backdrop brightness
- Previously all text used hardcoded grey values regardless of ElvUI theme
- Introduced `TH()` / `TM()` / `TD()` style sheet helpers — all label sites in the settings panel use these consistently

### Bug Fixes

- Fixed `RefreshOverlayBoxes` scoping error (nil call on login) — forward-declared as a module-level upvalue so it is visible to `LoadOverlayOffset` which runs at `PLAYER_LOGIN`
- Fixed overlay X/Y boxes not showing saved position until the panel was manually opened — boxes now populate immediately after saved data is loaded

## v1.0

*Initial release*

### Core Detection
- Four-gate lap detection — any gate starts and any order completes a lap
- 3-second per-gate cooldown prevents double-counting
- Mid-lap state saved per character and restored on reload
- Pending lap finish mechanic — all four gates must be crossed before a final crossing records the lap
- Detection scoped to a configurable zone map ID (default: 2393)

### HUD
- Compact flat draggable panel
- Live lap timer, last lap time, personal best, character count, account-wide total
- Four gate progress pips that light up in gate colour as each checkpoint is crossed
- Close button; reopenable with `/lap show`

### Gate Overlay
- Four screen-space gate bars rendered as coloured labelled lines
- All gates move as a single unit — drag any bar or label to reposition
- Overlay offset saved per character and restored on login
- Gate bars fade when crossed during a lap; restore on lap completion or reset
- Show/hide toggle in settings

### Settings Panel
- Gate names, P1/P2 coordinates (set from current position or typed manually), per-gate Apply
- Sensor width and zone map ID
- Gate colours with R/G/B input, live swatch, Apply and Default per gate
- Chat notification toggle
- Reset Gates and Reset Stats (with confirmation)

### Persistence
- Per-character: coordinates, colour overrides, HUD position, overlay offset, lap counts, best lap, mid-lap state
- Account-wide: total laps, per-character bests, zone map ID, sensor width

### ElvUI Integration
- Auto-detects ElvUI; reads backdrop, border, and accent colours
- Falls back to neutral defaults without ElvUI

### Slash Commands
- `/lap`, `/lap hide`, `/lap settings`, `/lap reset`, `/lap stats`
- `/lap mycount`, `/lap acctcount`, `/lap debug`, `/lap help`, `/lapper`
