[FEATURE] Empty layer auto removal

lyme74

Sometimes, I would paste a track selecting create new layer, or dragging track above to free out space for dragging other tracks

After dragging the track back to the original layer, the new layer stays, which makes the editor pane looks messy with too much of layer

Is it possible to auto remove layer when I drag or delete the last or only track away from that layer?

Or make it as a toggle option?

Right click in the Track list and there is already a menu item to Delete Empty Tracks.
