Just some suggestions after playing the steam version for 6 hours:
1) If you click on voting when some char is selected then it should immediately open the voting menu with this character selected.
2) Use power and abilites scrolling with scroll wheel is unuseable as it scrolls too much items at once.
3) Nation and province names on the global map when corresponding filters are selected.
4) Semi-tranparent UI side panels. Maybe 35%? Dunno.
5) Resources map mode (not really sure about this one)
6) Clickable buttons for map mode, like in paradox games. Hotkeys are good, but I think there still should be options.
7) Some sort of icons to differentiate between different event in the right bar. (Not sure about this one)
8) Ability to see/highlight hostile agents to the selected agent. (Map mode?)
9) Global map / ability to fast-forward world history
10) Pressing Tab key or Esc to quickly exit current menu
11) More connections between sea regions and coastal places of interest.
12) Maybe at least several turn (5-10?) cooldown between votes? (except for emergencies)
13) More indirect distractions for agents. Maybe bribing local guards, planting false tracks for a chasing agent.
14) I think it should be possible to select abilities and powers to use by clicking.
15) Temperature and habitality map modes.
