I have desktop with 3 horizontal screen, and only 1 vertical.

Now i move some item to top screen. Right now my page indicator show number 0 and -1. This is ok.

Now i enable seamless mode x (not Y). Go back to desktop. And here is first bug. I dont know why, but LL doing move item from -1 screen to previous position (0 screen).

Ok, i doing again move with this item to top (-1 screen). Now i must have in indicator -1 and 0. But i have -1,0, and +1 screen, this is second bug, because LL create new empty screen in bottom (-1). If i doing zoom to all screen, this screen is not visible (this is bug 3). If i put some item to -1 screen and zoom to all, now is this -1 screen visible, after delete item and going to zoom all screen isnt visible again. Pierre Hébert
