My comments (numbers show me commenting on said numbers)
OP:
1. I agree. Right now there isn't much of a city-management screen, which I would expect to house such 'next city' button. Really there needs to be a way to see all the information on the tabs at the bottom at once so you can really "examine" a city, rather than just glance at a few highlights.
2. heck I can't even figure out what the real difference is, other than some provide housing and some provide money.
But this goes hand in hand with suggestion 3. so all I can say is >>>> I AGREE
4. Capturing cities doesn't even really seem fully implemented yet. razing cities includes a loot system of some sort and a diplomatic reaction, all of which I think are going to come in a few beta 1 letters.
5. It needs to tell the players a lot of things it doesn't. It doesn't really address gold *costs* either. You build a road and it does take money (I think) but it doesn't tell you. This all needs to be fixed.
6. I agree as well. It also should become progressivly harder to make improvements. So it shouldn't just be it resets back a 3% of the research, it should actually go into a different system when it finishes a "trunk"
7. Its true. Along with several other "kingdom overview" type screens that let you see things like general magic power levels, army strength, estimations of population, and so on. or at least general "scores" of some kind.
8. It needs to ask you your first tech right away. I'd go as far as to say it should also make a bigger reminder everytime you've finished part of the tech tree, with possibly a Go-To link to let you change research subjects if you want.
Shurdus:
9. Again, I can't agree more. Like cities, I wish there was another option to view unit info than just the tabs at the bottom if I wanted.
10. I'm not entirely sure what you are suggesting. Do you mean like a "ping" on the... mini-map? (that would be nice). I'm sure when diplomacy is up, you'll get their face showing up to tell you whats up the way they do in Civilizations or MoM, and you will get to say you don't want war, even though I'm not sure why it even bothers to ask since if you DID want war you'd still say "I want peace" then march an army over there.
Madmelodie:
11. Lol, thats what I said 
But yeah.
Telefrog:
12. There needs to be a lot of recoloring of the map. I mean, cloth map is cool and all, but this cloth map seriously needs some dye. There should be color options for everything. I think a way to tell the borders is if the 'instide" boarder had some lines following it pointing inward. You see this kind of thing on terrain maps all the time to show sinkholes and such that don't go down enough to give a new height number.
Godixbis:
12. Another option would be highlight it or not. Perhaps give it an indicator light a sworling outline or something.
13. Or the "city screen" mentioned by me and Madmelodie that might include build options.
Hawawaaa:
14. Roads need to be worked with more. One thing I wanted to suggest though is possibly extending a city via roads. Like having a road go 2 tiles to a mine without having to go build a new city there or connect it with buildings. But that may be another discussion.
