It's been requested before.

If we're requesting what we'd like for it, though, I'd prefer it simply be a pair of "Save HUD settings" / "Load HUD settings" options allowing multiple named save files rather than tying it to what job we're on. That would give us a bit more flexibility.

That way, we'd be able to switch between layouts when we switch to a different role if we want, but would also allow switching when we want to hang out with our FC mates for a party or roleplay session and don't need all the same HUD elements we might during a dungeon or raid, and so on. We could have a dungeon HUD, questing HUD, and casual hanging out HUD, or whatever. It could also provide a good way to save one character's HUD and load it onto a new alt character.
