Reorganizing bookmarks that are in disarray could be made a lot easier if there was an option for ‘columnar display’ of folders according to level – i.e., having each successive folder level display in actual columns (left-to-right) according to their level in the overall folder hierarchy.
Right now, trying to untangle the logic of folders that can only be viewed as icons in the left column (Bookmark Manager) makes the project much more difficult.
Note that the columns display I’m suggesting would not have to include any bookmarks, just folders (all levels).
