A New Mount
[ A Hoverboard Mount ]
There is already a thin mount (the broomstick), so it wouldnt damage anyone having a hoverboard. The hoverboard could do occasional animations while floating or standing still, maybe some basic tricks. The hoverboard could also become a skateboard once getting too close to the ground, growing wheels and making our avatar occasionally kick the ground to boost themselves, and to return to the skies, we would have to hold jump
