I d like to make a suggestion about the sort in reading lists.
There is actually a sort by unread realeases but it's somewhat weird.

Why not sort by difference between the last chapter read and the last release.
So the series where you have many chapter not read will be put above those where there is only few realease since you last read it.

For exemple :
Yandere Kanojo color=red[/color] v.1 c.11
Nurarihyon no Mago [color=red](c. 112)[/color] v.9 c.94
Beelzebub color=red[/color] v.1 c.38

will be :
Beelzebub color=red[/color] v.1 c.38 (28 chapters unread)
Nurarihyon no Mago [color=red](c. 112)[/color] v.9 c.94 (18 chapters unread)
Yandere Kanojo color=red[/color] v.1 c.11 (6 chapters unread)

I'd like my list to have that too 😃
Good suggestion 🙂
