Enhancing stash tab affinity.

I would like to be able to use regular expressions in a stash tab affinity.

I.E. "Two Hand" or "Body Armour"

You could even use something that matched the item's prefix/suffix like how the search function works.

I.E. "Life Regeneration"

I think this would be a considerable user interface improvement and hopefully wouldn't be too hard to implement. :)
