Whenever you use a tiled window manager like Dwm, Awesome or i3 on your linux desktop, you might also want to replace or modify the default behaviour of the status bar. Usually you’ll display some common information like date, battery level or informations about your network connection.
Compared to the quasi standard program i3status, you can also use py3status as an external program to generate the status bar text. It has even more modules you can use to display additional statistics or functions. One thing I was missing, was the ability to easily track time so I modified the included timer module and transformed it into a stopwatch.
You can run or pause the stopwatch with a left click and reset it with a right mouse click. That’s all … very easy but also very useful ;) You can check out the source code here or just wait until module gets upstream.
