Would much like to have some kind of calendar report/bar diagram (time spent, mean CPM/WPM, errors rate etc. for each day) — like the one on keybr.com =)

P.S. Debian-based would be a more correct way to specify Linux distro =/

Thank you very much for your suggestion of improvement. Very interesting idea, we will think about it.

All the best from Berlin,
