Okay try this then
0 space in between the cells
original 36x36 sized hotkeys (guess I should have looked at the maintained spell window for exact size... let me know if you need them bigger hehe)
Left the bank in there for your scrolling pleasure
removed extra space... mostly... I left a 2 pixel space just on the edge to make it easier to navigate and adjust... also helps make it look a bit cleaner.
Let me know how it works for ya
