Especially for people with OCD on placement, it's impossible for example to place the contents gauge and contents action because the bounding box is ridiculously huge and there's no indication of where the actual buttons and gauge is going to be.

Same goes for all the buffs, debuffs, triggers, other buffs, cast bars, target buff/debuffs, alliance panels, notifications, etc.

Can we get some dummy items populating these UI elements when we enter HUD layout mode?
