I don't know if this is possible, but I like watching Neuro from another POV, like anyone that collabs with Neuro in MC. She's just too cute when watching her character from a different perspective. I searched whether it's possible for Minecraft to be in third-person view, and yes, it's possible. So, what I'm suggesting is having two POVs in the stream: the first-person POV on the main screen (big) and another POV in the top right (or anywhere) as a small screen for a third-person view of Neuro. That's it.
TL;DR: Suggesting two POVs in the stream: a big screen for first-person POV and a small screen (top right or anywhere) for third-person view of Neuro.
