Are you bent on launching your fave apps from the cube? I spent a month configuring my cube the way I thought would be best. Soon, I thought of a better set up, etc. Changing the cube is not as easy as setting up a bona-fide launcher, which I think you'll find is the best solution for your RN apps. You could try a simple app like tdLaunch, or go all the way with UltimateLaunch. There's a huge thread in the Software fourm on UL. Info on tdL can be found here:

Another thing you can do is organize your most used programs, folders, documents, spreadsheets, etc. for efficient file exploring with an alternative to WM File Explorer called GS Finder Plus. This can be made to be finger friendly, launched directly from your Today Screen with tdLaunch, so that you get something like the following with just one thumb tap from home screen:

BTW both tdLaunch and GSFinder+ are freeware apps.
Hope this helps, MrG
