I've been using the opensubtitles and (unsupported) podsnapi plugins for auto retrieval of subtitles. My wife and her family are Polish so ideally I'd like Polish subtitles for all my content where its available.
I'm currently only getting a fragment of subtitles retrieved but that's not an issue (there are other discussions on best practice and suggestions for increasing hit rate).
What I would like to be able to do is go into a Movie/TV section and filter the list by "With Subtitles" or even "With Subtitles in the following languages" with a checkbox list of inclusions.
The information exists so I don't see why this is not possible, would be interested to know if it's a feature that's been requested before or if there is likely to be traction based on customer enthusiasm.
