I like that my MBP auto-dims the screen and turns it off when the computer is idle. However, this is very annoying when chatting via Skype! Is it possible to disable this power saving feature only when Skype (or any particular program) is in use? I know it may seem petty, but I don't want to have to constantly move the mouse cursor around just to keep the screen from turning off, and I don't want to disable it entirely in system preferences.
