What's the use for this little lock in Framer alignment tools?
That's the point. I don't see the little lock making any difference when I toggle it on and off. Parenting, auto size and relationship with margins are ok, but they all seem to work unregarding of little lock status. So... what's the use?
When it isn’t locked and you move a layer it’s going to guess new layout rules. With the lock enabled the layout rules won’t change.
