Exactly what I wanted, great, thank you
It would be cool if it would highlight all HTML5 elements.. e.g. blockquote, cite, q, etc... now it only hightlights certain html5 elements. Also it would be cool if it would differentieate between sectioning content elements and flow elements.. :D

One of the best tools for On-Page SEO. Super easy to do quick and accurate checks or to do before and afters for screenshots. I use this weekly!
Удобно
very smart. must have for XML users. to the developers. Add a Dom Tree View and you will take over the market. we need to see the tags right on the screen. and we need a tree for when things get confusing
Sehr schön, macht genau das was ich gesucht habe.
