[Feature Request] An option to create/delete categories

[Dragowolf-dev]

This would be great. Currently, you can only add novels to either the default category or the completed category. However, an option to delete the default category, and create our own categories like Reading, Plan to Read, Backlog, etc. This is how Apps like all the Tachiyomi/Mihon forks, for example LNReader, do it.
