I thought of maybe some icon that would site in the tray and show the progress of the 10 minutes (even a single digit 9 to 0 to show how many minutes left is enough).
Or maybe an small progress bar that's always on top of other apps.
When it's time for a break, it should notify me somehow, but not lock the computer as the
TakeABreak , because sometimes we would want to continue to work for a few more minutes. (blink the icon?)
At right-click, there should be options: Start 10 minute work, Start 2 minute break.
Keep in mind, that when we get so efficient, we might want to change to (12+3)*4 or something.
