I was wondering if there are any plans to expand autorig builder with some animal setups as well like quadrupeds or similar?
Or even some facial setups as well?

We've made steady infrastructure improvements to ease the creation of facial setups in H22, factory-shipped autorig components are something that we would very much like to look at next. Quadrupeds are on the longer horizon.

Sounds amazing as everything form SideFX for a while now
Auto-rig components like eye, brows, mouth to start would be great to kick things moving in current direction making life easier and faster for more generalist oriented people, that don't really dive into APEX script depths
