Fred, it would be very handy to have "Rename" in the project manager popup menu. Even if all it did was change the name the project tries to access, and not the actual file on the disk, we could do a Save-As and not have to remove then re-add the file in the project.
Even more helpful would be a MessageRequester that asked if we wanted to...
a) Rename file on disk,
b) Copy file on disk to new name,
c) Only change in Project.
Thanks.
