This is a simple C# application to show a Pomodoro timer in the Windows system tray.
All actions are done by right-clicking the system tray icon, which shows a context menu.
To start a "Pomodoro" (25 minute timer), click the "Start Pomodoro" menu item.
To start a "short break" (5 minute timer), click the "Start short break" menu item.
To start a "long break" (15 minute timer), click the "Start long break" menu item.
Once you start a timer, the system tray icon will update to show how much time is remaining. Once time expires, a "Time's Up!" message box will appear.
While the timer is running, you can pause or stop the timer with the appropriate menu items.
The message box that opens may not open in front of what you're working on, and so you might not see it.
