[Feature Request] Downloading metadata for local manga

[Hunter-G01]

Request for the development of several features: metadata downloading, web-based metadata editing, and manga cover modification.

The metadata downloading feature ought to mirror what Jellyfin provides. Due to restrictions with current plugins, numerous websites are unsupported, leading to a deficiency in metadata when employing third-party tools for downloads. Manually inputting this information is excessively cumbersome.

Rather than altering the local code, there should be an in-interface manual editing function for metadata adjustments.

For manga covers, there should be an option to select any single image or any size to be utilized as the cover image.

I'm just using Jellyfin as an analogy, because in terms of its metadata download feature, it's the most concise, convenient, and easy-to-use among all the web platforms I've ever used. If other comic media libraries have better solutions, they can also be taken into consideration. Although online comics already have the feature to download metadata, the most critical point is to add the feature to obtain metadata for local comics.

Something like audiobookshelf would be pretty nice.

See image. We can search for the book title, and then it would autofill the metadata.
