As an enhancement I think it would be quite nice to have the option to enable pop up notifications similar to the style of msn messenger.

It's easy to find yourself looking alot at the time until the next break if it is in the status bar. With toast style pop ups instead, you wouldn't miss the breaks and it would be subtle enough to use at work.

Included on the pop ups you could have the various buttons such as 'skip', 'postpone' and it might be nice have a button called 'taking' as often when you are reading documents it starts counting this as idle time when you are not actually taking a break then you can be honest as to when you are taking a break rather than the system taking a guess due to you appearing idle

When a break is due the pop up could slide out of the notification area with the buttons skip, postpone and taking. If you skip or postpone the pop up will slide back and workrave would perform its normal functions until a/the break is due again. If you click take the pop up could stay and provide a progress bar to provide you with some indication as to how long you have left to take of break.
