It's non-intuitive that you have to press enter to activate the timer. I couldn't work out why making the text box lose focus didn't start it. I ended up having to read the source to figure it out! Also, it'd be good if there would be a way to start a new task after clicking "I give up"! Funny idea for a pomodoro timer!
LOL. We intentionally wanted to make the user feel like he/she is hopeless if he/she were to press "I give up" - ending it with a middle finger. Game over.
I like you!
