Visually it looks awesome, but what it really comes down to is the quality of the code. Most WYSIWYG editors leave a lot to be desired.
Second, I am always wary of amazing tools with unknown pricepoints. I get that you're still early, but some semblance of cost structure would be great. Frankly, I don't know if you're going to charge $1500 or $5 a month or free. I just don't know, there's too many ways you could choose to market this, and that insecurity, that lack of knowledge makes me uncomfortable.
That being said, great job on the concept and I can't wait to see what it looks like when it goes live.
