i3egg is an overly simple -- perhaps simplistic -- timer for i3.
It takes input like '0m3' or '4:0' or '15', waits the appointed number of seconds (3, 240, 900, respectively), and pops up an i3-nagbar when the timer expires.
i3egg has the following "features":
- No visible ongoing countdown.
- No builtin way to stop the timer once it has been started. (See: kill.)
- Requires i3wm (minimally, an implementation of i3-nagbar) to function.
It does one thing, and does it... welllll...
