When I open the forge dialog, I can see various item categories, and I can click the "fold" button (highlighted below) to hide and un-hide them:
This is incredibly useful, since that list does tend to get long and when I play a Demon Hunter I don't care about melee weapnos, when I play a Monk I don't care about quivers and mighty weapons, etc. etc.
Unfortunately this menu does not seem to remember which category was open and which was closed between game sessions, so every time I open it in a game it resets all categories to be open.
Is there a way to make it "stick", so it will remember which category was what?
