In 22.214.171.124, we release a feature to allow setting up a “All Manga (A-Z)” page which lists all mangas in alphabetical order, as you can see here: http://demo.mangabooth.com/all-manga-a-z/ I know some may ask what if I do not use English? The latin characters will not work for you, right.
Don’t worry. We already think about that. There is a filter that allows you to change the list of characters as you wish. You can ask this code in your child theme /functions.php file
return ‘0123456789abcdefghyjklmnopqrstuvwxyz’; // (*)
Just write all your characters in line (*). Easy, hah? With this filter, you can translate or add/remove characters if you like
Happy doing trick!
