Super awesome and very well done, just played with this for a couple minutes..love how you can choose the different platforms on the left and side and when you click on an element you can edit everything on the right hand side. How do you plan on monetizing this?
Looks great! One thing: Please don't force me to host my stuff with you. I'd rather pay twice to have the freedom to dl my designs. Also: Let me pay-as-I-go. As a designer I'd like to use this but I would not want to pay X bucks per month. I would pay X dollars per project.
Edit: After studying the video: I'll pay triple! Any thoughts on importing bootstrap?
We're actually big fans of the MailChimp pricing model (both pay-as-you go and monthly options), so it's a possibility.
About Bootstrap, the current demo already uses it for the non-visual elements (grid, etc), but we're still not sure about a whole-scale import yet. There are a lot of changes afoot with Bootstrap and Foundation (mobile-first being a big trend), so we're noodling on a ton of options.
Great work! I agree that importing a current site/design would be a killer feature. But, forcing to host is a non-starter...and would probably cause more issues for your company as well.
