Pomodoro like sessions; Break Timers

I think that it would be nice to have a break timer for ppl who like a pomodoro-like approach.
So when finishing a focus session, we could start the break (session?) and be alerted to restart the new focus session, also, after X sessions we could have a big break session.
with configurable options for small break session time, big break session time, and number of sessions before the big break
