Now that beta seems way more game like UI issues are becoming more distracting - at least for me.
It takes way too many clicks to either perform actions or get data. I know that elemental also targets netbooks (1024x600?) but it should probably use large screen estate if available (writing this on 1920x1200)
1 - there isn't enough info about what city is doing. HUD should include at least what is being build and if units are being trained
2 - there should be go to next (and maybe previous) city while on city screen
3 - when you click on screen there should be enough space on screen to display all buildings and all units. Currently it is:
click city
click build
click building
place building
while it could be:
click city
click building
place building
same goes for training
4 - How do you find city that has nothing to do? hotkey? icon on UI?
5- Spell casting UI is bad. So many clicks, small icons etc. There should be way to get from selected unit to spell casting immediately - and possibly not that small icons but icon + short description list or at least larger icons. There were favorite spells mentioned - that might help but I'd prefer direct access to all spells.
6 - Spell learning is not intuitive, I cannot figure out how it works and I don't want to read up on that. UI should make that obvious.
7 - How to select specific unit in group? Should be easy if you want to use special unit ability - it isn't. Probably needs hotkey and/or icon for next/prev unit. How do you target specific unit in group with spell? It seems that it just selected random one. Anyhow, not obvious.
8 - How do you move whole group out of city at once? I think groups should stay somehow liked even when entering and leaving cities.
9 - I cannot differentiate between bunch of people in one square and group in one square. You can move unit inside the square however 
10 - Health bars - at least opt-in? I cannot see how damaged the unit is.
11 - For some reason messages boxes on top right don't really stand out. Maybe is the whole Elemental color palette, but I think there should be some sort of animation (short flare?) when new messages arrive?
12 - Same for units and city icons on top left. No idea what to do there though.
13 - Next turn button should be in right bottom, so you can just pull the mouse in that direction. It is common UI experience practice to put very common elements on screen edges - so they are easy to hit.
I'll write more things that bother me later, after I play with the beta some more.
