I want to create a Panel with a lot of Objects and then move all of them at the same time just moving the Panel, without using Action for every single Object!
The only way is to put them all in the same Group? Cause is messy when you have different Panels made with the same Objects but different ID or Name.
There is not a way to pin, unite, freeze them all in a position and move them altogether?
This example describes the functionality you need: Pin object to another multiple parents
I think this is the most optimal way at the moment.
The Sticker extension does this perfectly. Once installed you add the extension as a behaviour to objects, and stick (and unstick) them to the panel with a single action. When you move the panel, the behaviour will move the object stuck to it.
