It's not a huge deal, but it bugs me that I have to re-set my sort preferences for equipment each time I go to that screen. When I was just starting out, I mostly wanted to sort by level. Now I almost always want to sort by tokens required, so I'd love not to have it reset to the default sorting by $ each time I leave that screen and come back. It would also make me happy if, within groups sorted by tokens, it would sort by level. I know that higher level gear is not always better, but I think it'd be a helpful approximation.
The 2nd suggestion you made has been asked like this: let us sort by more than 1 category. Both suggestions would be nice to have, yes
