Preserve component IDs when using "Duplicate Panel"
When using "Duplicate Panel," all of the components within the panel lose their IDs, being replaced with "Layer_23," "Rectangle_3," "Group_5," and so forth. The IDs are user data and should never, ever be discarded.
How am I supposed to remember, in a layer that has 100s of components, that "Rectangle_42" is the translucent layer that makes the group behind it appear disabled, or that "Label_12" is a FontAwesome icon for "Delete"?
Please stop destroying our work.
