Dragging multiple items to create lanes works fine, but needs some improvement as shown below. If i drag the selection from the top item, it adds the items one by one and creates 3 new lanes. But when i drag from the bottom or middle item, i can't add them all together. Also dragging the selection from the top item to the next track(or to create a new), and then back to previous track, it change the number of lanes from 3 to 2 and the bottom item is overlapped on last lane. However this doesn't happen if i drag the selection from the middle or bottom item.
