Some notes:
* Project generation with most of the features and a couple models is taking a really long time. I'm sure it's a background job, and I could walk away if I wanted to, but it'd be nice to know that the system would email me to let me know when it was done
* Sometimes UI widgets flicker when switching between sections. I'm guessing a lot of those styles are being added with Javascript, not CSS? You might consider switching to a CSS framework that gives you a good look and feel, but doesn't have to call some JS function to apply styles.
* The auto-capitalization on model names, and auto-lowercasization (?) on field names, was a nice touch, and made me feel happy about the product.
* It would be really cool if users could write and submit plugins / hooks. I'd be interested in background jobs that weren't DelayedJob, and deployments that weren't Heroku, for instance.
* I'm guessing that "public repos only" is a temporary feature, because GitHub doesn't have a way to authorize an app to write only to certain private repos, correct? Because most of my work is on private repos, and I can't see my organization using something like this without the ability to create projects (even scaffolds) privately
* A feature for Vagrant would be nice :-)
I'll be watching this! We've currently got several people switching from ColdFusion to Rails; they're good programmers, but they don't know the ecosystem or the conventions. This gives them a really good starting place. Thanks for sharing.
Edit: Also, this is the first time I've seen app/views/elements/, and I'm kinda pissed I haven't thought of using a different directory for partial layouts before. Now I've got some app/views/layouts/ directories to clean up...
