Additional Tongue Tracking BlendShapes
There are currently seven BlendShapes for tongue tracking which primarily only allow for inwards/outwards positioning.

Some further implementation allowing for simple lateral left and right positioning would greatly improve the potential feature applications.
Additional development could include both vertical and lateral manipulation, as well as morphing. This would be in similarity with competing HMD face tracking implementations.
