I note that we can keep movie extras in folders with different names, like "interviews", "featurettes", etc. Does Emby actually do anything different with the different categories, or does it treat all extras identically? If they're all the same, are there plans to treat them differently in a future version? I'm just wondering if there's any point to my classifying them all, or if I might as well be dropping them all in an "extras" folder.
