Right now volumes are not marked as unread, and x.5/x.1 chapters are only marked as their x value.

I'm currently reading the Overlord novel and I'm on volume 7 whereas /mylist still shows (c. 11) when that was back in volume 6 and concurrently it doesn't show (v. 8) as unread.

the volume issue is not as much of a problem with manga/manhwa as their numbering is usually continuous (an exception i remember is City of darkness Season 2 that started back from 1).

Hopefully this could get fixed to clear up some confusion some people have

EDIT: reading more and more novels makes this problem even more noticable and really hard to keep track of what i've read and when a novel gets an update, i had to create a custom list for novel to keep track of them better.
