Just a few things I've noticed that might make gameplay slightly better:

* It would be great to have some way of knowing which planets you have and haven't done yet with the seed vault. I keep just circumnavigating with it trying each system and forgetting one of them.

* I do know it's a game limitation but the sector size rule is difficult to work with when you have member worlds. Some mods have fixed this, I wonder if something like that could be accomodated?

* A quick-access button for institutions like the Federation Council would be handy.

* The AI overbuilds things like trading stations to the point you end up with 50 of them without realising.
