I was wanting to implement other members of your party to follow the main party leader (Similar to Deltarune and Omori). How would I go about implementing that?
I was also wanting to be able to switch out the main party leader and change the order of the party however. Is there a built in way with Ork to implement that easily?

By switching, do you mean changing the Battle Group? If so, that's also covered in that tutorial and is mainly accomplished by the Group Menu Part:

But if you mean switching who you are controlling and who is the "leader", then that can be set above, but also by some hotkeys under Base/Control -> Game Controls -> Other Controls -> Group Member Keys and Next/Previous Member keys
