At the moment nobody is really sure what is the proper term “StashID” or “Stash ID” and its usage in interface, documentation and even the development channels is all over the place. Lets change that.
There was previous attempt, but it got nowhere.
Stash ID (and StashID) isn’t a great name, since it really should be Stash-box ID - it’s referring to an ID on a stash-box instance after all. I think it was shortened for brevity.
Eventually, I’d like to convert the whole Stash ID concept into External ID instead, which would sidestep this whole thing.
