New to the game and just some observations

4th point: Eh? But you can save it? - its true initially you need to set up yours skills, but it makes sense as it is highly recommended to read your tooltips once while doings so. Then after it its there and stays forever. Or what do you mean?

OP is talking about saving the UI from one character, and applying it to a different character. Not setting up skills for different jobs on the same character.
While this is currently possible on PC, it requires digging into the game's directory, finding the correct folders for both characters, and copying one character's folders to the other.
