Hey Artico!
Sorry for the delay - I care a lot. And thank you for the feedback, it's great to hear :)
The things you're looking for are all goals for the next big version (0.4, but that number is really underselling the work that's gone into it)
There are a lot of changes in the works that make keystone more modular and enable customisation properly and as soon as they're finished we'll document how it all works.
For background - I get up to 50 notifications a day and am running on a few hours sleep at the moment. Currently doing a crazy amount of work to get Keystone 0.4 shipped this month. I'm also giving a talk about it in Sydney tomorrow night and in Nashville (at Nodevember) the weekend after next, to present our vision for it as the node.js community-powered content management platform.
So hang in there, we're nearly done, and don't worry - there's no indifference here, just a lot going on :)
- Jed.
