Make Reddit's Sidebar Retractable
If you do a lot of split screen Redditing, you'll quickly find that the sidebar can be a nuisance. Well, this script makes that sidebar retractable.
It adds a FAB button to the right-hand side of the screen which allows you to hide or show the sidebar. A localStorage entry's added to remember the sidebar's last position, so that you can browse the site without continually hiding it.
