Could you help us train our focus by making tracking internal and external events easier? Eg. buttons to increment / quick add an internal/external interruption to a pomodoro with maybe a quick note? And then show us stats of our progress / the number of interruptions (internal/external) per interval?
See eg. Scott Hanselmanns' really cool talk, this is where he explains this idea in 2 minutes:
I thought about writing a "Focus Trainer" Pomodoro app like this myself, but as I really enjoy yours and I think you're doing a great job, maybe that'd be another KILLER feature? Help people train their focus?
