We have been moving away from requiring Users to specifically activate features in favor of detecting when they need them and doing it automatically.
Examples at v14:
- When you create your second Company, multi-Company support is activated for you.
- When you create your second Warehouse, multi-Warehouse support is activated for you.
Examples at v15:
- When you activate your second Currency, multi-Currency support is activated.
So there is no longer a checkbox or a need to specifically activate the feature! (The Currency Menu is always available now, not just when the feature is activated).
Opting specific Users into and out of these features remains available in the Extra Rights section of the Access Rights tab on a User record.
