Not for importance or anything.. just what your top 5 used apps are. Besides the Google Apps.
Reason I ask is... thinking of putting more apps in my themes but I want to stick ones that are used a lot in them.
I will start as a guide...
1. Droid Forums App
3. Root Explorer
4. K-9 Mail
5. Our Grocieries
Once I see a few people naming the same thing, I will see about themeing the app.
