Hi all,
Is it possible for a `ProgramNodeContribution` to know if the user deleted it from the program list? Ideally, I’d like some sort of callback called when the user deletes a node, or some status flag that can be checked from withing a program node.
Thanks in advance,

Hi,
I recently searched for something like that, but couldn’t find anything. I think we can’t ☹

Another thing I found out is that whenever a program node is copied (copied only, not pasted), a new instance is created. When pasting, one more is created, so the one that is created when pressing `Copy` is never placed in the program listing.
Perhaps what I’d need given that is a way to check if the program node is present in the robot program’s listing or not.
