Yeah, I saw that page and it would definitely be useful to have in the sidebar. It would be way easier to use these attributes if they were documented in a table or something on that page so we can see them explicitly.
As an example, in the release notes for 4.1.1, there is mention of "Added an XML parameter for comma-separated keywords in AdView"; have no idea what the actual attribute is (though I could guess it might be "keywords") :-/
Keep up the good work and hoping you guys get some time to document these ;)
