Could I get some opinions on this so far? or some people to try it out?
Most everything is drag and drop (I'll be adding a non-drag and drop mode), all of the standard inputs work and are fully editable. Still working on the html5 inputs. Most inputs can be edited in-place or via the modal dialog by clicking the green cog. Whatever you enter/select on the actual input will be the default value, which you can clear by clicking the pink eraser. The white checkbox requires the input, the blue files clone it, and the X deletes.
The live forms are viewable at the url forms/ID or parsed into a post. There's no backend, so if you submit a forum it should just reply with an empty page with the results.
I haven't pushed it to npm, so pull it from github to try it out.
