well velocity for items would allow something like a shovel script that makes the items fly forward when link digs them up
I'm sure it would have other uses, however that is the only one I would use it for at the moment

also I have two more suggestions
is it possible to add link hitbox and speed variables in this update?
I don't know what the frequency of zc updates are but I really don't want to wait another 2 years for a update that adds this
