1) A button you can hold so that you can mouseover the monster info panel without it disappearing. Maybe Z or Shift or something. You don't generally need to do this often, but it would let you mouseover stuff like "burning" or "corrosive." The first time I found the Earthmother shrine, those plants confused the snot out of me because the Alpha didn't have Cursed or Corroded at it was not fun finding out what those did the hard way. :p
2) In the Menu uh...menu...put a Controls or Keyboard Shortcuts button to display stuff like the shortcut letter keys for spells (obviously number changes based on inventory position) and other information (like the keybind for suggestion 1.) This would be useful especially for things like if suggestion 1 already exists but I'm too much of a bozo to find it.
