I'd personally like to be able to hotkey buildings or units to select them. CTRL-1 targets Item Shop, F1 for teleport, poof I'm there. CTRL-2 targets "Bob the Rook", 3 cast Fireball, boom.
Maybe it's a skill I need to develop but it's so clunky trying to zoom out, scroll to your base, hit F1, and try to click the tiny little item shop correctly.
