Drag the bar to move it, drop the config panel

Position the bar by dragging (or click-and-holding) empty bar space
toward a screen edge, with a ghost slab previewing the target edge.
With drag for position and double-click for transparency, the bar
config panel, its inline gear button, and the omarchy-launch-bar-settings
CLI are no longer needed.
