"That is a lot of stuff to keep track of. I worry about track data becoming lost or corrupted when a track is not frozen."

Jim, have faith smile We always take risks doing similar operations. For example moving digital photos, videos, documents. I mean, if it is done and tested well, risks are minimal. Also UNDO can be a part of equation.

"There are a minimum of two elements in each track"

Yep, that is good point and this could be handled to a user advantage too. It could have a Copy (Delete, Cut etc.) "all" with these (parts you mentioned) checked by default for simplicity: Copy A, Copy B, Copy C , or individually checked/unchecked manually for custom selection.


--------------------------

In my view, it has to be "simple enough" for casual user to understand the workflow, otherwise it might be a very narrow request for something very specific that not many people will have use for. Jim, I am not trying to bust your request, it is good, but hoping bigger picture can be seen. Just my 3 cents.
