The application loader will essentially work like a big folder: slide up to see the apps, slide it down to dismiss them. There are also basic audio controls. We wish we didn't have to slide the panel all the way up just to get to the controls, it might just cause too much screen clutter, but that's almost a non-issue.
Graviboard:
There're four different types of Gravity that you can enable, the default being Earth, the others being Moon, Zero, and Custom. Custom allows you to adjust a decimal value as to the amount of gravity present, which is a nice touch by the developer.
SBrotator:
It's a jailbreak tweak that brings iPad like landscape homescreen to the iPhone, as well as allowing all apps to work in landscape view. The tweak allows you to fully customize your homescreen any way you like and it is now fully compatible with iOS 4.x.
