Tutorial - How to set Default Abilities

By default Game Kit Controller loads all the demo abilities for you to use or alter. If you want to clean out the list just follow so.

On this list, you can see the all examples usable out of the box. So you can remove any of those which are enabled by default, each of those abilities has an ability-enabled field

With that as false, the ability is not usable and can be unlocked by events or anything similar, including the experience or skill system for it.
