definitely useful for getting help.
its also nice if you make considerable changes to a BP and might want to take several quick snapshots to before changing things so you can have a reference of where you came from.
Not all the helpful ppl at answerhub want to open their editor and paste code into it to see the BP. It’s sometimes just easier to look at a screenshot the in need person posted and say “move this node to here and this one here”
etc.
