We just launched http://nightly.enyojs.com, where you can find nightly snapshots of Enyo core and official libraries, as well as the API viewer, Bootplate, and Sampler code.  Use this to test your app against the bleeding edge or just see what we’re up to, without needing to pull from GitHub.  We plan to keep about 2 weeks of archived snapshots available there as well.  Head to the forums to let us know if you have other suggestions for making Enyo development easier!
