This editor is a free and open-source online tool which lets you design html pages with an interface very close to dreamweaver's or powerpoint's one. But we've put a special touch in it ;)
The HTML5 editor is now available online and called Silex. Only developers will want to download Silex source code from github.

Overall impression is that this behaves more like desktop publishing than webdesign, in that the layout assumes printing-press style fixed page dimensions. I guess if that is what you want, OK, but it is not the intended role of HTML5. Also has a few serious issues like local links being auto-prefixed with 'h t t p ://' -which means they will not work.
