Wishlist sorting question

It would be convenient to hide games in which the user is not interested.

...you know you can click the eye icon next to the game/giveaway's title to hide all giveaways of that game, right?

Have you tried using search parameters?

Like example, giveaways of games released from start of 2017 with minimal metascore 80 open for users having level 1 or higher (with entry cost 10P and above):
https://www.steamgifts.com/giveaways/search?release_date_min=2017-01-01&metascore_min=80&level_min=1&point_min=10

You can tinker the search request for your taste to see less results and bookmark it.

I mean i'm not too sure what you're asking, a good place to start if you haven't already got it, I would recommend getting ESGST, which has a bunch of filtering options which may help you.

I don't understand your question properly. Do you wish to hide all games that are not in your wishlist?

UPD: There is a page https://www.steamgifts.com/giveaways/search?type=wishlist, which contains giveaways of games from my wishlist. I'd like to know if it's possible to get the same page but with exactly those that aren't in my wishlist (i.e. only giveaways that DON'T SHOW on the first page). Something like this.
