itch.io really needs to enable "NOT" statements on its browse pages instead of just "AND." This would do a lot to make the default "Popular" filter useful.
It also really needs to give folks the ability to hide games based on specific criteria.
There are certain people who I try my best to totally forget the existence of and I'd rather not see games that support or oppose them (filter out based on word in title/description).
There are devs who make both fun action games and creepy nasty shit (filter out specific dev).
There are games I already own that have been stuck in my Recommendations for months (filter out specific title).
And, while a lot of game jams produce amazing work, there are certain specific jams which absolutely do not (filter out games submitted to a specific jam).
