I have an idea, basicly in the pet menu you can choose to normal mount your pet and flying your pet, so you can fly your pet. press space to fly up or something.
With a permission of course

(This is a suggestion and not a issue)

Flying and riding is combined and controlled by the Config File. I'll add perms for this soon

Full flying support added. See the newer Dev Builds. If it's not what you were looking for, reopen this 😉
