[BUG] Scratchpad Rename dialog

When I try to give a note in my scratchpad a name that contains a colon (":"), it brings up a dialog labeled Scratchpad Rename that tells me the Filename can’t contain any of the following characters: />?

Nowhere does it mention the colon character. There may be others that are forbidden as well. This dialog should be updated to list all the characters not allowed, I think.
