It is annoing that I can't use anymore long-press button to split a screen - which was more than much easier version than the newer version.
Also what I've noticed is that I can not close used programs one-by-one. If I want to close example just only one program, then actually I have to close all the programs.
Why the hell to ruin something that works more than wonderfully?!?!?!?!?!?!?!?!
