Once everything is ready, we should definitely discuss a change in the keyboard shortcuts. We should have shortcuts for each menu, because one can use the arrow keys from there + Enter. Even Ctrl+Enter for exiting a game will work.
We might then lose some other shortcuts if we're running out of letters in the alphabet. I think we could then also remove the toolbar-related shortcuts from the Encyclopedia, because they are clearly visible on each menu item.
We will also need to update the basic control tutorial, because I have removed census & statistics from the fieldaction menus.
No menu background planned at this time. We can certainly think about it for a follow-up branch though. This branch is already getting quite big
