The HUD displays everything. Both "hotbars" can be edited regardless which mode you're in. The numbered "hotbars" are the elements used by kb+m players, but "cross hotbar" is the element used for controllers should be available. (In other menues, it's called the X-bar". They don't truly replace each other. Just gotta keep scrolling through to find "Cross hotbar" to move that guy around. If you're using W-Xbar options and want to split that from the main cross bar, that's under the character or system settings to split first, then you should be able to edit it in the HUD editor.
