Show control shortcomings

The show control implementation is well done, I like it!

There are to my opinion 2 important shortcomings:

1) there is no warning to save the changes. F.e. when you shut down the console without saving, all changes are lost without warning.

2) there is no feature to copy/backup the complete show including snaps, snips,...

It would be nice to gets these features soon. It would give much more security.
