When you click the "Abandon Colony" button and you get the "are you really, really, sure?" pop-up, would it be possible to add a list of what you'd be deleting to the pop-up? Something like "Are you sure? This action will permanently delete 5 research facilities, 20 construction factories, and the 1st (Guards) Infantry Brigade"
Not that I just abandoned the wrong colony out of two on a planet or anything. . .
