It would be much more useful to have the ability to move the icons. WoW puts temporary action buttons directly in the way for the icons, making them impossible to see

Yes, you can move the displays with /hekili open, or set specific coordinates for each display via /hekili > Displays.

You can? Type "/hekili" in game without the quotation marks ofc, Then you're able to move the positions and plenty of other things.
