This problem is very irritating; these panels are basically vital to the way I create levels, I would hate them to be removed and I will be using an older editor version for now as they are unusable. Just don't let the panels be resized or something and give an option to turn them on and off.
I have to kind of agree. While I think I could live without the panels I definitely find them very useful.
Disabling the ability to resize them would fix the hotkey issue. And I never need to resize them [now that they are an appropriate size unlike in old Lemmix].
Btw; might these glitches have anything to do with a point about how the hotkeys work: certain
hotkeys like "select all terrain, [T] select all objects (O)" only work if the windows are NOt in the pannels at the bottom. while they are some of these keys Instead select different forms in those pannels. (I might have this reversed) Much how on many windows programs, like firefox for example holding down ALt then F key selects the File menu.
