Holy wow, great work guys! This is exactly the type of tool a lot of designers are looking for to bridge the gap between design and code (or at least get their feet wet before diving into it full-on). Hopefully this will get more visual artists using services like CSSDeck and Codepen, unless you plan on venturing into this realm yourselves to allow the community to create assets for everyone else to use - which would be fantastic.
Personally, because I still prefer writing from scratch, I'd use it after I thought I had a good framework coded up already just to quickly tweak it and try out some other ideas. Not sure how you plan on monetizing, but a tiered system for those of us who wouldn't use it to create from scratch would be appreciated, even though I'm not sure how you'd determine that (imports only?).
