You can create manual lists , I'm doing that for now too . You'll find it in the homepage in your profile bar as "List" . I'm adding my mangas in different categories for now. Also if you have a android device ,use the mihon app to store mangas in your library , then track them through mangaupdates , the new list stays secure . And it won't cause glitch here in the website .

Guys we don’t touch our lists right? They said just bookmark things right? I’m not sure I’m not adding anything just in case it affects the site
