That actually would have made it much, much worse, assuming it wasn’t already a bug that was in for correction when I checked in on it (it was).
It’s very easy for us to “add stash tabs” in the visual, you-can-see-and-access on an individual basis sense (which is what you were seeing). It is an entirely different thing to add functional ones that won’t break the game once the patch goes live.
So no, adding a stash tab that hasn’t been prepared for that scenario would not have been a good thing, nor would it have magically solved the issues we’ve already gone on, at great length, about as to why this is not something we’re looking to add right now.
That hasn’t changed; if it does, we’ll communicate very clearly and intentionally about it.
