Ability to pose and animate rigged models

It would be great if when we upload rigged models (characters usually in Tpose) we had the ability to pose them straight from the 3D editor. And if at all possible, being able to keyframe poses and create an animation.
Currently I have to pose externally, then upload to sketchfab, then decide that does not look right, repose, reupload etc.
I see that we are able to view weight painting and bone structure from the layers view, so perhaps this is already something being worked on and I was not aware of.

Thanks for your suggestion! That functionality is not currently on our roadmap.
