I like the idea of a "poof". So how do I get it. "created a layer just for those tracks" is the mystery for me. The piece of track is invulnerable to any deletion or movement. I can connect to it but deleting the connection has no effect. Could you expand on what/how you did it. Also, I should note that I have never used layers since any attempt led to me making common corrections, or additions, as if I was in the base route - grrrr.
