The download Spirited Away (for Mac users) appeals to my need to be organized with my just as great need to have a lot going on on my computer at once. It hides inactive applications that you have open, but don't want to close.
Spirited Away's settings let you decide how long applications can be inactive before they get hidden (up to 10 minutes), and lets you exclude applications you never want hidden (like for me, I wouldn't want Firefox hidden).
It's being able to have the necessary apps open but having an uncluttered desktop. Spring cleaning, here I come.
