Yeah, I know the issue has been mentioned ad nauseum on these forums, but I just wanted to cast one more vote for being able scroll the main map with the keyboard. I like using the click-grab technique some of the time, but I've got to save my pointer finger's strength for clicking on ships, planets, menus, and rotating my custom ship designs. Keyboard scrolling of the main map would spare me some (literal) pain - allowing me to play for longer periods of time!
