It is awesome! Definitely one of my favorite uses of the API. Thanks to Code Dev you can queue your Skills and keep on learning. Unlike the Greasemonkey Scripts that allow queueing this even works when you're not on the Glitch website. No more keeping your computer running at night to start learning your next Skill at 3am :)
