As a Learning Technologist, I sometimes have to help other members of staff with their Xerte projects, and I end up being co-author on a lot of things that I don't need access to any more. It would be great if I could remove myself from a project so that it no longer appears in my files once I have finished helping on it.
It would also be useful to be able to 'lock' a project so that once it is published and in use I can't accidentally delete or alter it. I'd want to be able to unlock it if there were any changes that needed to be made, but having an extra step before being able to change things on live projects would make me feel a bit safer!
