Really appreciate the detailed feedback.

* Email on generation is a good idea. Also, I don't have a Gem cache system yet which will help.

* Flickering is because some of the inputs have to compute a lot of values @ Backbone model layer. Definitely opportunity for optimization.

* Thanks :)

* A lot of users have asked for user contributed features. The problem is it's hard to extract an API from my generation system but I hope to in the future.

* Very doable. I just haven't written private repo support in because I'd have to deal a lot of auth/selection issues which isn't a priority right now.

* Vagrant would be great.

For a lot of these, I just don't have time yet but all candidates for the future.

Thanks again.
