Like the ignore function in Steam. Itch does not have that.
I made a client side tool that can do that. https://itch.io/t/3477347/add-an-option-to-exclude-owned-games-when-searching
You need a browser extension that can run tampermonkey scripts. Read here for an explanation how it works https://itch.io/post/10216613
That's a feature they should copy from Steam!
I am not even sure how I purge my suggested games. The site features to suggest new games could be heaps better. The way I see it, because it is not so prominent, people use browse to search games and then complain about lack of exclusion of tags and that they always see the same games on page one and that there is so much horror and visual novels and such. This does just not happen on Steam. I never even used a tag search on Steam for years - I did not even know it existed.
