So this is regarding those times when a user is holding command and dragging an audio segment up or down the grid (not left and right) in order for it to not move.
Currently there is no specific sign that makes sure that the item wont move and so i find myself looking at the 0.0.0.0 to see that i did not accedently move it lest or right instead of up and down.
So how about a deferent colour while dragging the item up or down, or a lock sign during the transition.
