Would like to assign certain functions into hotkey. Such as plain paths and Cutting down trees. These are important when pause function is disabled.
You could map the F1 - F10 keys for selecting buildings (in the low row) to get people really into the flow of building stuff and make it even more satisfying. Say I pressed F2 and then you could let me use the tab key to quickly cycle the buildings from left to right.
Definitely not high priority in the grand scheme of things but a lot of the fun in the game is to get really into the flow and you as coders surely know that flow feelings are produced using a keyboard, not a mouse.
