I read mostly webcomics and they're typically separated into seasons rather than volumes, so it would be nice to be able to increment seasons instead.

If it already has chapters or volumes, you could always add another text field(Seasons)in the same format, not deleting the other measurements so to speak.

workaround suggestion: Use the v counter as a season. The counters are for personal use so as long as you know what it means for you then it will work for that purpose.

Yeah, there are many ways to get around the issue, so it's not urgent by any means. I just think that with the increasing popularity of webcomics, it would be helpful to make "seasons" an official option.
