As part of the new improvements to the default UI in Dragonflight, Blizzard added support for hidden action bars to momentarily appear when you are actively dragging a spell, so that you can still add a key bind while keeping bars hidden.

I think it would be nice to have this feature baked in Dominos' action bars. As a workaround currently, I have a macro that toggles action bars when I want to edit my key binds (in case anyone has the same need).

This should be pretty easy to do. I'm already using a [cursor] macro to handle showing the buttons, so I could use it to override show states too.
