I have a tonne of items in wishlist (mostly things I think are somewhat interesting, but often either I am waiting for a sale or for another year of development)

I would love to be able to filter it down for items that I am currently interested in. Like being able to search for vr fps games on discount with at least 80% positive reviews. That would be insanely useful for me, and in theory would make more users buy more games, and make more users comfortable filling their wishlist with tonnes of games (meaning tonnes more opportunity for a sale)

So yeah, filtering by multiple tags categories would be massive, as well as searching for minimum/maximum review score, ascending descending (for both wishlists and store search). It would also be cool to similarly filter for early access games which haven't seen updates in 12+months etc
