Dev,
Request 1 - Would it be ideal to download the nzb from the indexer(s) base on dates. I notice a pattern as the older the file the more likely it would be bad. If it says it was released today for example, 12 hours ago, it would most likely be good.
Request 2 - Alternate naming for a series. From some indexers, I get no result for a series while in some I find because each one of them has the show as different names. It would really be useful for shows release in other countries as well.
Example: Animal Kingdom (2016) vs Animal Kingdom US
