Ive never had any HTML5 lessons...

...and I was able to build a complete page just with this app! There are just a couple of problems. First, Id like to be able to search by what the tags DOES, also. For example, if I search "comment", I want the tag to show up. And second, it doesnt tell you everything. I had to use Google to find out the tags "title" property. But other than that, its amazing.
