You can delay your turn, there is no bug.
As per the helmet switch, it wasn't there in the first opus also. Annoying for sure but hey, not as painful as not being able to fast travel.
As for the skill, I thought so (didn't play much on keyboard), so yeah, the autofill is to be changed for everybody!

(honestly, I think this is even more annoying with a controller since it's not that easy removing an item from the hotbar)
The thing is I don't think a lot of people is playing with a controller, but this is pretty much the only fun way we found with my friends to play with 4 people in the same room so yeah... We'd like at least the bugs to be adressed...
I'm hoping those will be adressed, but I don't know. Nobody from Larian seems to roam around here, and when I see the bug section, I don't know when this fast travel thing will be fixed... :'(
