Make the "Timer Running" indicator more visible.
Make the "Timer Running" indicator in the top bar much more visible. The tiny green dot that pulses is really easy to miss for me. I would prefer to turn the whole clock green rather than just a small dot.
Also, it would be nice to have a configurable pop-up notification for "timer still running".
Another program that I use actually puts up a notification, and if the timer is running for a really long time, sends out an SMS notification.
