[Bf-funboard] Copy Transform Constraint needs Offset

[Hadrien Brissaud]

You're right, the copy transforms constraint does not allow any editing to
be made on top. Furthermore, the offset Ajlan is talking about can be
achieved by selecting "local space" in the constraint settings. However,
child of would not be appropriate in certain cases where you need the child
to mimic the parent's transforms but not rotate around its parent's pivot,
which is what would happen with a child of constraint. Anyway there's your
answer Ajlan !
