Add a menu to your GNOME Shell for the application Variety.
I plan on submitting this to the GNOME Shell Extension website.
Download or Clone the repo, copy the folder variety-menu@oscardomingo.com into ~/.local/share/gnome-shell/extensions/; then restart your GNOME-Shell (Under Xorg: Alt+F2 -> r), then you will be able to enable it through GNOME Tweaks > Extensions.
