I know this is currently done by holding Z and scrolling with the mouse, but I have 2 questions regarding this function.
Firstly is there anyway I can set it so I don't have to hold down Z and just zoom the map by scrolling the mouse wheel? I checked the hotkeys and couldn't find anything.
Secondly is there anyway to set the zooming so that it "bumps" the camera as you zoom out? So it doesn't get stuck on map edges, forcing you to move the camera about before zooming further?
