I am using 3 walls as my basic background for apps.
- after installing an app shourtcut forces to create 4th page. testes difrent configurations like middle screen as 5th or 1st..
- home button or either main screen can not be seted. it always goes back to first screen.
useing this button as a return to 'puplit' works well, it's going back to the screen you had before
running app, suddenly another push mess it up, first screen again.
