-A confirmation dialog before the user overwrites the current simulation (with the one-click square to the left of the "save as" function).
-Would it be possible to have Undo able to undo multiple times?
-Middle-clicking an empty space would make the secondary element eraser.
-A display view with NO effects, just plain pixels. Like the Heat view with color.
-Preset keybindings (custom would be nice) --Ctrl+N - New simulation (with confirmation box before opening new simulation) --Ctrl+S - Saves (with confirmation box) --X to switch primary and secondary elements --D to make secondary element eraser. --Shift+D to make secondary element wall eraser.
EDIT: -It's impossible to stop the saving of a stamp right now (it says right-click, but it doesn't work). Possibly ESC to stop the process?
-The stamp browser only supports 8 pages. Is it possible to have more pages displayed?
