I'm new to webflow and I'm already inlove with the functionalities here. I'm used to building bootstrap sites from scratch. I've tried a BUNCH of other bootstrap prototype tools/web app, but your Webflow is way beyond better! Yep, I said it.
However, and I believe a lot of other web designer's here as well would love to have
PSD INTEGRATION Functionality added into webflow designer. Not like Adobe Brackets Preview(PSD Integ.) functionality tho its good to have as well. But Even just to use the PSD template just to gather the layer name and put it into the class/id, relay the size of the element and the font styles (Google font integ would be cool as well). I know this is so demanding of me but this is just a suggestion that you might love to do as well. =)
Great job with the Webflow, Webflow Team! I give it 8/10. and Merry Christmas!
