I searched plugins, ideas, etc. and didn't see anything similar so I had a new idea for a plugin (although I couldn't create it because I wouldn't have the time nor the technical skills requred to implement it).
Anyway, I thought it would be nice to keep track of all our site's earnings from Google adsense, banners, paypal, etc. right from the dashboard. This way we dont have to have 10 windows open just to find out how much we make every day.
