I'm getting behavior where, if I try to work with clips in the track without lanes expanded, the clip I'm working on will sometimes crossfade with the muted clips below it.  To have audible clips crossfade when I overlap them is exactly the behavior I want, but I don't always want to delete the unused takes from a track before working on it, or to work with the more complex lanes when I simply want to do a quick edit, or to clone the track and archive one version while deleting the extra takes from the other.
 
Is there some way to archive the lanes themselves, so that they remain in place but cease to be factored in to any editing decisions?

Hi. This is just a guess, but have you tried to lock the clip?
All the best.

ah thanks, I do believe it will work to lock the unused clips. 

If it doesn't work, someone else will probably know how to do it.
All the best.
