New to the game and just some observations

[Ransu]

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.

Documents > My Games > FFXIV > Character folder.

You don't have to do any kind of crazy digging lol.
