Hello! I think AI has answered my question, but I wanted to run it by you folks just in case it’s wrong.
You’re describing the default behavior of the WoW UI frames in Edit Mode when multiple frames are active, where the Extra Abilities frame maintains its position and pushes other frames upwards. While you can freely move the Extra Abilities frame itself to wherever you want it to be, the default priority order of the frames themselves cannot be directly changed to make Extra Abilities inherently “move up” while others stay put when they are all enabled simultaneously.
Think of it like this: Each frame has a base position, and when multiple frames are enabled and potentially overlapping, the game’s UI logic determines how to position them to minimize overlap. The default logic favors the “main” frames (like the Extra Abilities frame) maintaining their intended positions and moving others out of the way.

In summary, while you can’t change the default priority of the frames, you can achieve the visual effect you want by manually moving the Extra Abilities frame to a higher position in Edit Mode.
