I'd like for, like in galactic civilizations 2, a prompt to come up when a constructor has made contact with a spacestation. As I am a busy emperor with things to focus on other than spacestations, I need the fact that the constructor has arrived to be delivered to me so I can decide what to build (or to withhold on construction). I often find myself forgetting that i've sent a constructor to one of my many dozens of spacestations, and I do not realise until I click on the station many turns later and find they have 3 constructors waiting for use.
