One of the nice things of the demo is that you can see the code that generates the elements. Unless you pick php.. then you don't get examples, not even a link to the php documentation.
Yeah, inline examples preferably, that show me how this button with progressive flag that i'm looking at was ACTUALLY written in php.
Or at least per component linking to the specific class in the php doc. Not one link in the header that is "he, here is the index for all the documents, good luck finding the classname (that we didn't tell you about) of the component you were looking at on the previous page and already forgot about"
