IMHO MACAW is a quantum leap in graphically based drag and drop progams. It has great support and some excellent tutorial videos. Although I haven't bought it yet (it's US$179 and I can't justify that as I'm retired now and most of my sites are pro-bono) if I get the requirement for a responsive site from a paying client then I'll buy it like a shot. I've looked through the tutorial and dl'd a fully functional demo (yep they do that) and I'm confident I could be up and running with it, with references back to the documentation, in pretty quick time. And I bet I'm older than you
But I would rather stick with NoF as I've been with it since 1996 and was a beta tester while it was in development. I'm loyal in that way; NoF has given me a living on and off for nearly 20 years and I'm grateful for it. But I do believe the two together, NoF and MACAW can answer 80% of a small site developer's needs.
