Does not have enough types available, need services and other useful types.

Used it quite extensively. now it doesn't do more than tell me there is a schema on the page but when i click tester, it says there is no schema on the page. so the two tabs do not talk to each other or something. I know it is free, but I get more from the google testing. Going to miss seeing it in my extensions bar.
