Feature request | Manga Playlist

[Aetherryu]

I've been using Rulia for a while now and its been the only manga reader that solved the many issues I have with other readers. I'm hoping to request just one feature:
A playlist system: Currently my manga files are all over the place and I often switch between different series for a change of pace. So I'm proposing a system that lets us create a custom the order of manga, rather than following the sorted order of a folder.

Thanks!

Thank you for your advice, it really is agreat idea. I hope to make it excellent so it will take some time to implement. The bookshelf also needs some UX tweaks to make it easier to add files to the playlist.
