Currently the pomodoro timer only tracks focus time and short breaks. It doesn’t track pomodoro “sets” and the longer break following a set.
My proposal is to add options for how many focus sessions to a set (set size) and time length of “long breaks”. Additional functionality would repeat the “focus” time equal to the set size and follow it by a break of the “long break” time length.
This is all descrbed in brief on the “Pomodoro Technique” wikipedia page.
