Say you have like 9 or 10 tabs worth of a festival's pets. A normal stable can only go up to 8 tabs. You could buy a new stable but it's kinda irritating to split up the collection between two stables. What if for a diamond cost you could continue to buy tabs?

I figure to protect the incentive of buying stables these tabs will be pretty expensive in comparison to buying an actual new stable but they're there to save your sanity when trying to organize.

not something I've personally run into (yet?), but I'm generally in favor of more options for stable customizing

I generally just buy more stables with dias. I would reallly like 10 tabs for a total of 250 in each stable though. 8 is "uneven" and it bugs me. Darn ocd, 5, 10, 25, 50 75, 100, 150, 200, 250 etc in 50 lots xD why?? No idea
