Dreamweaver is still very much usable: 1. Get a copy of Dreamweaver 8, or 9[1]. 2. Switch it to 'code' view only. 3. Install the HTML5 intellisense updates.

Dreamweaver is still very much usable: 1. Get a copy of Dreamweaver 8, or 9[1]. 2. Switch it to 'code' view only. 3. Install the HTML5 intellisense updates. 4. Create a new 'HTML template' that has HTML5 header tags. 5. Enjoy! One perfectly good and usable HTML/JS/CSS editor, with what I feel is still the best intellisense for CSS around. --- [1] '8' is better, as it's before Adobe took over, added bugs and renumbered it '9'. Seriously... they are functionally the same product.
