Hello, I just installed KoReader on my Kobo. I am delighted with the functions. But one thing bothers me a lot: On the home page, my library only displays folders and not the cover of the books (on my Kobo, the books are organized in folders by author).
NB: with the native operating system, the storage of my books is identical and yet it is the covers of the books that are displayed in my library and not the folders.

I create a new collection and add all books from a folder with its subfolders.
But it brings all types of files back into the collection, not just the epub or pdf extensions.

Do you have a solution to help me resolve this?

Thanks.
