Hello! First of all, thank you for developing this software. It helps a lot. I'm not here to ask anything, but to give you some advice.
A lot of people are asking you for new websites to add. And I think it's just the beginning; this software is becoming very popular, and people asking for new websites will increase too. So, you should deal with it just as Tachiyomi (an android manga reader app) did: instead of making a new function for each site, they created functions that work according to the structures of the sites. For example: a function for FoolSlide-based sites; a function for My Manga Reader-CMS-based sites; a function for Wordpress-Manga-based sites, etc. This way, they don't need to add all the sites that use FoolSlide or the other two, since their app recognizes it and behaves accordingly. I think you should do something like that. Sites that use their own structures are very few and can be dealt with or just refused; but, if you added support for all FoolSlide-bases sites (for example), it would address a lot of requests and you wouldn't have to deal with them anymore.
