Wow, I'm extremely impressed that you're still updating this application.

Just upgraded from 3.2 to 3.3. and it's great to see you being so proactive with your customers feedback.

I think this is a perfect utility for time management and can only think of a couple of things I'd like to add ...

1) I hate clutter my dock, could we have the option to have TU sit in my menubar instead?

2) I'd be nice to have a timer start when another finishes. After my 30 mins of work I take a 5 minute break so it'd be good if i could loop the two timers in a 'playlist'.

Apart from these suggestions TU is by far the most practical application available. Keep up the great work.
