Gnome Shell has beautiful and functional interface, but without extensions it can be quite boring. If you are like me, by now you are probably amassing few Gnome Shell extensions and managing them all is not going to be easier, then you need an extension to monitor all of your extensions in a glance .
Extension List by Amanda will do just that, it lists all of your installed extensions and their status (on,off,update) in Gnome Shell activity overlay.
I am aware that it can be done via Advanced Settings or via Gnome Shell web interface, but if you like to have great desktop theme integration then you'll like this extension.
