I have a request. Ambient Facilities affect every character in the sector -- but the Player has no idea because nowhere during play can they find that information. Ambient Facility description tags do not show up in game. So my request is to have the Ambient Facility description show up in game like non-ambient Facility descriptions do. I'm hoping it's an easy modification.

I'm afraid it's not that easy, especially for someone who never worked with assignments/facilities code. If this feature will be implemented in the trunk, I could port it to +AI, but developing it for my project is low priority at the moment.
Also, you can probably just add facilities which no one can use but which will show the player the effects of ambient facilities in this sector.
