Search for gem tags or sort by gem tags in gem stash tab

It would be really useful if we could either search gems by tag or filter by tag in the gem stash tab. Overall I'm kinda disappointed in my purchase of the gem stash tab, as it's hard to find what I'm looking for in there unless I know exactly what I'm after.

As an example, currently searching for 'minion' returns all gems tagged with 'minion', as well as all gems that say 'cannot support skill gems that create minions', which is the opposite of what I'm looking for (pictured below).
