>that once you've checked off all the pomodoros ... the task is supposed to be done

Not really. I manage tasks in a todo manager (Trello), pomodoros are just for time tracking (100h+ working hours per month, 6h+ per working day, so it's 200/12 in a 30-minute pomodoros). It really helps to estimate my progress and schedule stuff, planning free days, limiting working hours not to burn out, etc. Or at least it works for me.

Thank you very much for all your points and suggestions, all of them have sense and are helpful! I really do appreciate it.
