As you might know, I'm working on the refactor for ATK.
Here is blog post explaining the update: http://nearly.guru/blog/ui/progress-update-jan2017
The strategy is:
- create stand-alone implementation for Agile Data and Agile UI
- re-integrate so that you can use it optionally in ATK4.4
- include Agile Data / Agile UI as default in ATK5.0
I don't have the timeline for 5.0 just yet, but Agile Data is complete and Agile UI is nearing completion. You can try it from anywhere, just follow documentation.
