Macaw is looking very good
I've seen a couple of demo videos now from Macaw, which is a new web design tool that is under development. I'm very impressed. Not only with the interface but also with the code that it produces. Anyway, here's their latest demo video.
I think Macaw is due for release in 2014, initially as Mac-based version but with a Windows version following on. I'm looking forward to trying it out!
