For starters, a change of view such as a grid would be so much helpful, especially for the ones like me that have a super long list of wishlisted games.

Then, I would love to have other sorting options, such as Descending Price criteria. Yes, I would like to see the pricey options first because I would have an idea of how much content the game has, or roughly the game´s quality in general, etc, etc, etc.

Finally, (for now), to be able to use the search bar exactly as it works outside the Wishlist section., especially for the contextual results. (i.e. if you are looking for a game featuring a mansion and a female as protagonist, you would type it and you would get that, or similar results).
