We can right-click on HUD elements to toggle on/off, it would be intuitive if a third mode is added to the right-click: demo mode.

And let the target and focus target demo modes be repeatedly casting a 6 second cast.

And don't forget the content action HUD.

Lastly, a snap-to toggle would be nice. Let HUD elements get a "snap-to-grid" mode and "snap-to-element" mode, so I don't have to squint my eyes to know if my hotbars are lined up properly.
