It appears that MC's Rename, Move & Copy tool doesn't support client copies.
This would be super-handy.
In fact, I'd kill for the Rename, Move, and Copy tool to be fully functional from the Client-side (able to move stuff on the server, initiated from a client). Okay, maybe not Kill, but it is something that makes it challenging to use MC18 at the office the way we are for managing content on our streaming servers (where the final path counts).
I should start a "Things I'd Like for Rename, Move, and Copy" Thread, actually... There's a few more (reasonably minor, at least compared to that request above) things I'd love in there...
