I’m sure I’m not the first to request this but every year during my important sporting events (cycling) I add files to my plex so I can watch them on my TV and every year Plex spoils the results by showing auto generated previews from each file. I’ve disabled every available Library option for previews/thumbnails and invariably they are still there. This is MADDENING! Plex devs, please provide an option to simply not show or generate these thumbnails/previews/posters/etc!
Also for whatever it’s worth, if the platform was open source I’d be happy to contribute the feature myself. Let us nerds help you.
