What problem is this feature intended to solve?

if someone wants to have the variants button still but they don't want to go back to 1.21.5 or earlier, they can toggle a setting that will bring the variants button back. plus the variants menu is a bit broken sometimes, because when i kill a normal pink pig, i unlock the hairy one instead. or if i kill multiple villagers with different jobs, i still only have access to one type of villager, which is the unemployed one.

Describe the solution you'd like

just add a toggle feature somewhere that makes the variants button appear in the menu like it did before the 1.21.8 update, or keeps it off like it is now.

Have you considered any alternative solutions or features?

The Variants Menu shows the same variants as the menu did before, since both use the same backend. However, due to some coding bugs in Minecraft, starting with 1.21.5, it is not possible to render the same entity type (e.g. two villagers) in a menu at the same time. Therefore, I had to remove the variants button and adapt the variants menu.
In fact, the reason why there was no update for several months was, that I had to rewrite some rendering technics of Mojang so that at least multiple different entity types were rendered correctly.
