Youtube prefixes their bookmark titles with a number in parens (e.g.: (23)) that represents. I think, the number of times this file has been referenced at the time it was bookmarked. If I sort the bookmarks by name, this number makes finding duplicate bookmarks by sight almost impossible over a non-insignificant number of bookmarks. Is there a way (e.g.: an addon) using a regular expression to delete the prepended numbers from all the bookmarks in a folder? I believe I can backup the bookmarks in JSON format, run a regexp in notepad++ to delete the leading--and useless--numbers, delete the existing bookmarks (backing them up of course in a virginal JSON), and reload the bookmarks. But, I don't want to do that if I don't have to. I didn't find an applicable thread.
