I have a little Suggestion/ question. When interplanetary travel is released into the game, would you have to scroll out of the planet and zoom into the 2d system? Because if let's say your moon base was under attack, you be able to do a simple double click onto the moon in the sky, or have to take the time to zoom out and zoom in. I was thinking something like universe sandbox styled zoom in would be useful in quick situations.
It might also be good to be able to make control groups of planets. Be it that 1-0 can be buildings/groups/and planets, or if you could hold down a key which would allow you to select an alternate set of 1-0 (i.e., 1—commander, 2—factory, shift+1—Planet 1, shift+2—Moon)
Maybe something along the lines og the "pie control" seen in newer versions og android and Castle Story? I think this might be used elsewhere in the game aswell.
