[Feature Request] Add option to retrieve metadata from www.wlnupdates.com or www.novelupdates.com

[Emasoft]

Please add the option to retrieve all novel metadata (alternative titles, author, first published date, genres, summary, series, etc.) from www.wlnupdates.com or www.novelupdates.com and save those in the epub metadata.

Both of these sources link to many different websites and makes it virtually impossible since the code will never be able to accurately guess where the chapter content is. Additionally, the goal of this app is to provide a way for a user to download and read novels for personal use only and I don't think additional metadata is necessary.

You just need to get all the epub metadata from the novel web page on novelupdates.com or wlnupdates.com. Here is a real world example from an epub:

<dc:identifier id="book-id" opf:scheme="ISBN">1234567890X</dc:identifier> 
    <dc:title id="english">Battle Through the Heavens</dc:title>
    <meta refines="#english" property="title-type">english title</meta>
    <dc:title id="original">斗破苍穹</dc:title>
    <meta refines="#original" property="title-type">original title</meta>
    <dc:title id="alternative">Fights Break Sphere</dc:title>
    <meta refines="#alternative" property="title-type">alternative title</meta>
    <dc:language id="text-language">en</dc:language>
    <meta refines="#text-language" property="identifier-type" scheme="onix:codelist22">01</meta>
    <dc:language id="original-language">cn</dc:language>
    <meta refines="#original-language" property="identifier-type" scheme="onix:codelist22">02</meta>

All the metadata in the example above is taken from Novelupdates.
An extensive API is provided on both websites. You can check wlnupdates.com API here:

Oh, I think I understood your original question wrong, what you mean is when the app download the novel from other sources, lets say Boxnovel, there should be an option to add additional meta data from these sites correct? If that's the case, I think its doable.
