Me and my colleagues often place holds for our patrons, and more often than I'd like to admit, we forget to add a holds note before placing it. Then it would be useful to be able to edit the hold, add the note and save it, instead of the workflow now where we have to delete it, add it again and perhaps change the priority to make it as before. I don't know how difficult if would be, but it's a regular request I get from colleagues.
