It took a bit of getting used to, pretty different from divinity's UI but after getting used to it (10 hours as of right now) I like it, my main gripe is with the hot bar, really tiny ability icons randomly thrown in with items scrolls etc.... and the more skills and items you get the messier it becomes. I guess I could take some time to organize it, but that seems like a chore. Especially since you have to do it for each character.
I kinda wish it broke down / sorted into categories. like spells lvl 1-2-3 ect, items, scrolls. maybe each page dedicated to certain options. Maybe an auto sort button like the inventory has?
