Masking models (at least for portraits)
 

In light of the Dragonflight UI overhaul (pretty exciting!) I'd like to request the ability to mask models the way we can textures; or at least a way to provide a circular mask like we could before the new masks with SetPortraitToTexture().

One of my addons (Adapt) replaces the texture portraits with models. With the slim/modern borders around the portraits in the default UI, there's less artwork to hide corners behind.
