If I create a new set of paths, click [Render Camera Path] (floppy disc icon) -> [Add Current Configuration] -> change name -> [Add to Queue] ... that persists.
But if I open Render Queue, and edit the name of an EXISTING item, that does not persist.

Ah, I see I should have created it as a bug report here :)
Thanks for copying my Discord post over. I'll follow this for updates!
