Suggestion:
A privacy oriented, lightweight, FLOSS, self-hostable front-end for JAVLibrary. (Similar to Invidious, Nitter, Bibliogram, etc.), however this would be for JAVLibrary.

This reason behind this is, it could provide users a more privacy friendly way to fetch database data into programs such as Jellyfin, for this type of content.
It would also provide a significantly better browsing experience, and could offer list tracking. Maybe some kind of federated feature over ActivityPub to connect with others, leave comments, and discuss stuff too.

This could possibly be extended, to be a "mega-frontend database". So for example, it can grab information from many database sites, such as AniDB (For Hentai/Anime), JAVLibrary, Caribbeancom, TheMovieDB (For just movies), TheTVDB (For TV Shows).
