Workaround: Bookmarks separators

Until we have proper separators for the bookmarks pane, here is a decent workaround:

Bookmark anything (It can even be deleted afterwards, it doesn’t matter) and then just change the name in the bookmark pane to make it into a separator. I recommend including some unicode to really make it pop out (see below - different coloured flags might be nice of course, the possibilities are … large). Enjoy!
