Definitely need to be able to hide stuff. I have a ton of fluff that I looked at once and will literally never look at again. That's the nature of a lot of stuff on itch. It's not meant to be something long lasting. A lot of things here are transient and they're meant to be transient. I've also got a metric butt-ton of stuff that I tried because it was free and simply did not like it. I have searched for this and there are topics going back at least a YEAR asking for the option to hide stuff.
Come on, itch. Get on it.
