An option to have Expression Point Control move with the layer position
For example if you were to use the Point Control in animation you might set it near the knee of the puppet. Then move the knee with the Point Control. However you move the Puppet to another place in the composition the point control would currently stay locked and not move with the puppet. It would still control the knee but it wouldn't be visibly near the knee as it was before. This optional non-fixed position would give the object a hidden AnchorPoint/parenting that meant the the GUI for point control would move with the puppet but values not change until directly interacted with. Another option would be to allow the point control GUI to still be visible when its written expression contains "Value" (self-referential value) so that a user could use expressions to write this feature in themselves and still be able to see the GUI for point control. Currently GUI disappears when an expression is applied even if the expression is just "Value" a.k.a just referring to its own value.
