Broadly available "searchable" list
Incorporate the ability to narrow down or only display broadly available titles. Searchable by genre as well. (i.e. Horror Broadly Available) AND ability to search by region.
OR, better yet...
Allow titles to play based on STREAMER. Yes, viewers still MUST have prime linked to Twitch, however, viewers should not be blocked from watching a stream because the title is not available in their region. They are still watching a STREAMER'S channel. Watch Parties should be STREAMER based. Eliminate the region locks all together. Viewers are still paying for their prime service and proving that by linking. So Amazon is not losing any money and neither is Twitch.
