So I know that almost everything in your hoard has a tab, but I really think a tab just for items used for breeding, changing fertility, upping mutation chances, and the like needs a tab for itself other than being lumped into the Other Tab. I've had a few times where I've had to scroll through a fair bit of items to find an IBF or a Hyena Meat, even in my Other's Tab because I don't like to bury these items in case I forget I have them and go to buy more.
It would also be helpful during events where you can purchase the items that ensure certain genes are passed, effect the amount of cubs and genders the cubs may be, as well as items that pass stat values.
