Adds the button to ElvUI's anchor/mover system, disables native dragging so it doesn't conflict, filters the now-broken "Reset Position" dropdown entry (scoped to this menu only), and raises the mover overlay above the minimap so it's grabbable in config mode.
Strips the native tooltip-style backdrop pieces off the LayerPickerFrame button and applies the ElvUI backdrop/button style, gated by a new Instance checkbox in the Skins tab.
