Graham just showed me this cool alpha project from the Gnome team. As you can probably guess, it's a web portal for Gnome Shell extensions. This makes it easy to see which extensions exist, what people thought of them (there's support for comments and ratings), but it also lets you install them straight from the browser!
All you need to do is visit an application's page, and then click the little on-off toggle at the top left of the page. I tested it with the alternative status menu, and it worked almost instantly. A little feedback about whether it suceeded or not would be nice, but other than that it's pretty cool.
Just a little something for you to enjoy this weekend...
