+A monochromatic Pomodoro timer widget with per-note time tracking and automated report generation. Built with zero external dependencies.
 
 ## Features
+
 * **Pomodoro Timer:** Standard 25min focus / 5min break cycles.
 * **Per-Note Tracking:** Automatically logs how much time you spend on each note while the timer is running.
 * **Monochromatic UI:** Uses the active theme's CSS variables for a distraction-free experience.
 
 ## 🚀 What's New (Latest Updates)
 
+**v4 - Native Widget Panel**
+
+* **Right-pane widget:** Replaced the absolutely-positioned floating button with a proper `RightPanelWidget`, rendering the timer as a native collapsible section in the right panel.
+* **No more overlap:** Removed `_autoposition()` and all manual coordinate logic — the widget now follows Trilium's layout system naturally.
+* **Cleaner UI:** Timer display enlarged to 32px; controls expand to full width.
+
 **v3 - Core Bug Fixes & Stability**
+
 * **Wall-clock time tracking:** The timer no longer stops or loses time when the Trilium window is minimized or loses focus (bypassing `setInterval` throttling).
 * **Pause fix:** Fixed a bug where time wasn't accounted for correctly after unpausing a session (`lastTick` reset issue).
 
 **v2 - Workflow & Persistence**
+
 * **Seamless Transitions:** Automatically chains sessions (Focus → Break → Focus) without stopping.
 * **Safe Persistence:** Saves progress to `localStorage` on pauses or app closures. The timer automatically restores pending data if you reopen the app.
 * **Auto-Reports:** Generates a formatted note on stop, detailing completed cycles (and if they were chained), total time, and time spent per note.
 
 ## Installation
+
 1. Create a `JS Frontend` note.
 2. Paste the script code or import the `.zip`.
 3. Add the label: `#widget`. Reload Trilium.
 
+> To place the widget in the **left pane** instead, change `get parentWidget()` to `'left-pane'` and the base class to `api.NoteContextAwareWidget` with `doRender()`.
