"Cool Timer" has a countdown timer with alarm that's helpful when waiting for "GP" to replentish. Not like waiting 4 minutes in game is hard, but when in windowed mode, you can surf the net and then come back with full "GP" when the alarm sounds.

Beware there's a lot of extras you don't need during install.
