Rather than writing a ton of posts, I though I would combine several suggestions into one. Because I'm lazy.
1) The inclusion of a mini-map would be the, coolest, most bestest awesome change in the whole wide world and I would love you forever if you could include one.
2) Make the building queue click and drag. I occasionally need to reorder what is in the queue for various reasons (going to war, need a better economy, researched something better etc.), but I don't want to delete everything already in it and have to click the buttons again to do this.
3) When you find a "Map revealing a new city" or "Reveal the location of another channeler" bonus on the map, I think it would be nice to scroll to where that location is. It would help understand where it is in relation to me. Especially important if I have found more than one. I might not remember which is the old and which is the new.
4) Some sort of reminder when I have enough spell points to research a spell. The spell point bar is so unobtrusive that I often forget I need to keep up on learning my spells. Maybe have it change color or glow or something when I have enough points.
5) On the subject of the spell point/research bar, it would be nice if clicking anywhere on the bar took you to the proper screen to modify/research what you are doing, rather than the tiny little button that is in place right now.
6) Some colors of borders are kind of hard to see on the map. I sometime find myself blundering into another sovereigns territory by accident because I can't see their borders real well. There may already be an option to change this.
7) It seems sort of strange to me that you can build more than one town hall per city. It's kind of one of those buildings that you would only expect to see one of.
