I'd also like it if auto end turn went away. Something I find annoying is I'm not often given time to upgrade a newly built starbase. If the constructor was the last idle ship and I turned it into a starbase, the auto turn kicks in while I'm trying to select starbase modules.
I think there is also a problem if you colonize a world that you want to turn into a core world, but the colony ship was your last idle ship.
I'd like it if they made 3 buttons: One button for end turn, another button to move all ships with move orders, and finally another button for managing idle ships, planets, and shipyards.
