1. Overall the UI is not that readable: I'm never sure who's turn is it, whether or not I made an action and/or move - I know that there are icons and the speed bar, but they should be more prevalent
In the beginning intro they mention shared turns so multi people can take there turn at the same time. Now I'm not sure if its related to initiative so people roughly around the same turn sequence can act or if any can act at the same time. Also I doubt this but never really bothered to check, say if I pass does that end my buddies turn as well?
It is related to initiative - all chars with the same initiative roll can work simultaneously. And ending turn doesn't end other player's turn. What I mean by this is that there should be notifications like "Player 2 is waiting for you" and "Waiting for Player 2...".
5. I'd love to have the "cycle current character" key
This is in the game.
It's not. There are "Next char" and "Previous char" keys, but no single button for cycling between them.
11. In the inventory screen sometimes I see all characters, sometimes only mine - why?
Might be related to ownership of npcs/pc characters
What do you mean? What I mean is that sometimes, when I go to the inventory screen I see only two of my characters and two placeholder windows for the characters controller by other player. But sometimes I see all 4 of them - and it's not related to the character proximity, like I thought initially.
17. When guest player wants to skip the dialogue line, the host should see that it's OK for them to skip
voting system
Voting system can tell you that other player is ready to select dialogue (and which line they prefer), but does not allow to communicate the fact that I already read the subtitles and want to skip the dialogue to next line.
