BookmarkSwitcher switches the content of the bookmarks toolbar with a folder called 'BookmarkSwitcher' in the bookmark menu. If this folder doesn't exist it will be created. The bookmarks are moved one by one to preserve the order they are in (added bonus: looks satisfying).
About the license: for now it's all rights reserved, because I don't really know the difference, but I'm very open to suggestions.
About the icon: The icons are from Google Material Design iconset, and are used under the terms of the Creative Commons Attribution-ShareAlike license. If you have better icons, let me know.
If you have requests, you can always try to ask (no promises though), and if you want to collaborate, let me know!
