Full Screen Remotes


I am currently using version 2 on IOS 7.0.2 on ipad 3.

Can someone please explain how to get the remotes to go full screen. I have one remote for XBMC which is probably the smallest setup which spreads across 2 columns in landscape mode but others which use all panels and have extra rows of buttons remain as a single column. I cant work out what is required for full screen.
