A great feature would be if bookmark menus could be set in different colours, not just individually, but also so that parts of a bookmark menu could have a certain colour. In this way the categories and subcategories of bookmarks would be identified much faster.
So in these bookmarks menu for instance, "DICTIONARIES" could have one background colour, and "SLANG" another. (As it doesn't seem possible to take a screenshot of the bookmark menu in "work mode" I have attached a copy from the bookmark library.)
