I think it would be convenient if Sick Beard would check Netflix, Hulu, and Amazon Video when you are searching to add a new TV series. Personally, I don't feel it's necessary to download a series if it's already available through those streaming services. Though I know there are some others who strongly disagree with that mindset.
My idea is to have sick beard check Netflix, Hulu, and Amazon Video when you search for a show on the Add Shows page.
Then have an indicator next to each search result that is available on those streaming services.
Users would need to setup their login's in the Config area, which would tell Sick Beard which streaming services to check.
See the attached screenshot for an example.
