As the authoring tool is still some time off I thought it'd be worth updating my old Sublime Text Plugin for version 2 of the framework. It's a collection of snippets that I originally made last year which drastically improves build and population time of Adapt courses. It has all of the new syntax for Adapt 2.0. To install it, you should use Package Control with Sublime Text 3, just install "Adaptionary".

Here's the official link:

Hope this helps some people!
