[Bf-committers] Why is use fake user not default for actions?

[CoDEmanX]

I agree.

However, this can be fixed with a simple addon, core code:


from bpy.app.handlers import persistent

# Auto-enable fake user to rescue unused actions
@persistent
def fakeuser_for_actions(scene):
     for action in bpy.data.actions:
         action.use_fake_user = True


This addon needs to be enabled by default to ensure it always sets the 
fake user!

Either way, I agree the old system might be best for this. User experience/ frustration > consistency imo. =
