If in cfg_statusbar.lua I set fullsize=true, split at root stops working. Tested in ion-3rc-20070506.
A lesser problem is that a root split doesn't do anything when there's only one frame. A behavior that you may or may not consider a problem is the way such splits are merged. If I split the screen twice normally, a frame always merges with a frame that is adjacent to it. If I split the screen twice, but the second time is a root split, the right/bottom frame merges with the left/top one instead of with the middle one. ~fantasai
