As the game develops your city screen (assuming you don't hide unconstructable buildings) gets very cluttered with greyed-out buildings you cannot choose to construct. Now, I for one like to keep unconstructable buildings showing so that I can see what I WOULD be able to construct if I took certain actions (changed civic, got some resource, built some pre-req, etc.). However, with some recent changes (late V15 I think) there has been an explosion in the number of buildings that are unconstructable and likely to forever remain so. This is because a huge number of buildings now require vicinity bonuses (different flowers or fruit orchards for example). What I would like to do (simple code change) is to slightly modify what gets shown (when hide unconstructable is not set) to omit things with unmet vicinity requirements (which [aside from Great Farmers at least] you cannot influence anyway). It's easiest for me to just change the code to do this unconditionally, but if people desperately want to see all these other unconstructable buildings please scream and I'll make it a global-define option like I did for alpha-sorting.
