[FR] Add flowmodoro timer #87
Description
It's similar to the pomodoro technique, but lengths are variable each "cycle".
When you start flowmodoro, stopwatch starts. When you take a break, timer starts for a specific time, dependent on the work time (typically 20%, but I think that should be configurable).
The benefit of this flow is lack of "flow state" interruptions. Unfortunately it's not very popular, so I don't think this should get high priority
