A) The first link for "Built-in filter" has 2 critical limitations: 1) The person posting the fix admitted it's only useful for ONE exclusion; and 2) when I clicked the "x" by "Romance" on their own example... itch.io removed the syntax for the exclusion. That means, in order to maintain ANY exclusion, you must have it in the device clipboard, then re-add it to the url every single search edit. That means that, even now, 8-YEARS after their post, this function is still Very limited natively. That doubles the search inquiries for one search edit. (search-term; exclusion; change search; add exclusion; change search; add exclusion). Why is that ok?
B) The second link for the browser extension isn't much different on exclusions, as the extension's developer said 2 years ago... "
Questioner: killkrazed 2 years ago: "So the tag filter can only filter out a single tag at a time? There is no way to get multiple tags filtered at once? (not referring to the genre filter, but tags like "2D, Visual Novel" etc)
Developer: redonihunter 2 years ago: "The feature was implemented by Itch's leafo some 6 six years ago, or so I understood. It never got a gui or was advertised much. Or expanded to work for more than one tag.
"The only thing my homebrew extension does, is to use a feature that is accessible by extensions to modify urls persistently. And attach an input box. So you can write in the tag and browse with the excluded tag and do not need to modify the url each time with copy paste.
"With a bit of legwork you can simulate filtering multiple tags with the third tool, the tampermonkey script about the ignore list.
"Basically you search positive for what you want to exclude. And then scroll down in endless scroll for a bit and then go to top again and press and hold 2, while the css is display: none for list 2. This will add like 50 items per second. Rinse, repeat, for more tags. You can save the lists for later use and import them to combine them differently.
"Of course this will not update automatically for new games. But the popular list is ranked by popularity, so you need only add a couple hundred of the top items of the unwanted tags and the top does not change much."
{End quotes}
That sounds like a lot of legwork to "Simulate" just one more exclusion. The verbage says it's for tags, not categories or genres. The fact that itch.io hasn't added that in 8 years, and my comment suggesting it being met with "Isn't this half-assed garbage work-around enough for you?" is absurd. I'm not looking around for something that only works well for one term. I'll just keep looking.
