1) very minor issue: if you have trade+defensive pact+open borders with a leader, apparently there's not enough space in the "score bar" to show the attitude smilie, and it shows a dot instead. btw, the unhealthy smilie used for cautious seems out of place. FF has varying levels of smile<--->frown that look better imho, maybe you can take the icons from there
2) one gripe I have with the current autocast system ( as much of a godsend as it is ) is that it looks kind of unelegant to have 2 icons with the same picture in the list of "stuff you can do" , plus, and more importantly, it's not easy to understand if a unit has autocast activated or not. I suggest that "activate autocast for spell y" gets an icon which is the same as it is now, but with a green V that makes it easy to understand it activates autocast. similarly, to deactivate autocast for spell y, the icon has a red X on it. this should be easy enough and make it a lot easier to understand at a glance what each button does.
3) another "display issue": I'm playing without "more mana" , but my palace description says it gives 5 kinds of mana. the additional 2 should not show up in the description if not using that gameoption, it's misleading.
4) the more I think of it, the more I think that a gameoption that makes ice+creation+force+possibly dimensional buildable instead of wild mana only would be a good idea. I, for one, would always enable that
5) not sure if it's possible to change the way "citizen automation" works, but it would be nice if cities would prefer to use a specialist instead of working an unimproved tile. a specialist is definitely better than an unimproved tile, but right now citizen automation doesn't realize that, so you have to micromanage cities to make sure that they're doing their best. also, artist specialists should probably be considered inferior to other specialists ( culture is not as useful as hammers, gold or science imho ) , but still better than unimproved tiles, due to the fact that they generate juicy great people points
