I don't think adding the year would be hard. I need to set up my dev on my new computer (RIP laptop that was my best pal for years), but after that, I'll be able to play around with it some. Each item has it hardcoded what year it was made (well, the full date to be honest) which is how we do the tabs for a lot of the holiday shops. As far as individual tabs, like for Cash Shop, that might be a bit more work. I'll play around and if I can't figure it out, beg Bug haha.
