I didn't have anything too particular in mind, although I do find the Emloop beep to be a good one (nice and quick, yet audible, and easy to keep a rhythm to). I think an option to turn off the beep would be nice too, and I still like the idea of having the text box containing the timer flash with every passing second (text box background changes color during some interval like [sec - 0.1, sec + 0.1] or [sec, sec + 0.2] for each of the last 10 seconds... not sure if 0.2 seconds is a good length; it's just what I though of off the top of my head). Again, it would be nice to have the option to turn it off, since I can see how some people might find it distracting. Thanks for listening to my ideas, and good luck!
