Missing one feature - but otherwise great!

I love this App! However, the one thing that it needs is an option to go negative once the time has run out. As it stands now if you dont see it hit Zero, you have no idea how much time youre over. It could be one minute over or 10 minutes over, you have no idea because it hits zero and stops. Id also like the option of having a beep at the Yellow and Red warnings so that again, if Im not look at it I get an audible warning. Add these and Id gladly give it the 5th star!
