I would have liked it the jQuery API documentation would be closer to the PHP.net documentation. For instance, I want to know the options for $.post - going to http://api.jquery.com/post/ would sure be nice (and even if it didn't exist, it could do a search for "you might have meant...")

For people unfamiliar with PHP.net's configuration, going to php.net/<function or whatever name> will go to the function if its known or search if it isn't (like http://php.net/strapos)
