Great app actually, used it in developing and it's working mighty fine!
However, it's a bit hard to use and can sometimes be unworkable with.
I would give a suggestion for A separate tab for Pomodoro, I think it's quite silly that all pomodoro timers are always tied to a task. Sometimes I just need to turn it on quickly and focus. Also it took me a stupidly long time to figure out how to use one.
It would be also good for an option to maximize the Timer instead of having it on the side, I found it disappointing that I couldn't move the borders of the timer.
But overall, a really nice application made by a smart witty developer. Thank you very much for bringing this software for our use.
