n00bcodr/Jellyfin-Enhanced ? reverse-engineered prompt

Build me a Jellyfin plugin that makes the web app feel way more powerful and polished.

I want it to add useful quality of life features like keyboard shortcuts, better subtitle styling, richer movie and show pages with ratings and reviews, poster tags for things like 4K HDR and Atmos, spoiler hiding for shows, bookmarks, and a live view of who is watching. It should also integrate with Seerr so users can request movies or shows straight from search and detail pages, including things like specific seasons or quality options, and let admins approve requests inside Jellyfin. If possible, add a media calendar and download monitor from Sonarr and Radarr too.

Make it work as a server side plugin so everyone on the Jellyfin server gets the features without installing anything extra. Give users a simple way to turn features on or off for themselves, and keep everything optional so the server admin can control what is enabled by default. Use the current Jellyfin docs online if you need to.
