 ## Unreleased
 
+### Added
+- **Windows tray popover, settings and Capacity Dock follow the shared language.** The surfaces #1608 left in English (the popover, General settings, and the Capacity Dock window) use the macOS menu bar catalogs, including Traditional Chinese. Settings → General → Language writes the same `language` key in `~/.config/codeburn/config.json` that the desktop app writes, and a change made in either app is picked up while the tray is running. (#1646)
