Comment 54 for bug 1672139

I've got some working code that I was going to submit to Phabricator, but I thought that I would check here first on the protocol for context menu changes. I opted for a "Reveal in Bookmark Tree" context menu entry in the Library that would navigate to the appropriate place in the tree and then highlight the entry in the right-hand panel (this seemed more sensible than devising a new window just to show path). Is there some specific vetting process for menu/GUI changes? Are there other reviewers other than Mark or Marco that need to be included in the commits?
