Taskbar Timer

A Windows 10 system tray countdown timer. Shows hours remaining as a number inside a color fill that drains like water from a glass as time passes.

Inspired by traytimer (Linux), ported to Windows.

Features

Visual countdown — tray icon with color fill that shrinks over time (green -> yellow -> red)
Set duration — minutes (25), hours (2h), seconds (90s), or target time (14:30)
Preset durations — 5, 10, 15, 25, 30, 45, 60, 90, 120 min via right-click menu
Hover tooltip — shows remaining time + elapsed time
Pause/Resume/Reset — right-click menu
Persistent — timer survives app restarts, adjusts for time elapsed while closed
Auto-start — optional Windows startup via included VBS launcher
Alert — beep + flashing icon when timer completes

Requires uv and Python 3.13+.
