The Activity and Manga in Progress sections don't track volume progress.

When reading long running manga e.g. JoJo One Piece Id like the to track my progress by volume As the volume as I tend to read one volume at a time. However currently If start counting up in the volume filed the Manga in Progress section of the home page still shows 0/whatever chapters. I think it would make more sense for it to switch to 1/whatever volumes and let you progress with the plus button one volume at a time. Also Id expect there to be a notification in the activity log when you finish reading a volume.
