I’m surprised I didn’t see it mentioned here (unless I missed it) but I use the “hide game” function liberally. Anything I’m not interested in, gave up on with no chance of trying again, completed with no desire to revisit, or won’t touch for any other reason just goes away, out of sight. It helps give a real sense of progression through your collection and you can pare it down to favorites you would likely revisit and things you have yet to play. And the hidden tab is easily viewable if you ever want to look at everything for any reason like rethinking putting a particular game in there.
My hide game is for a porn visual novel i tried out once cus i was bored and horny and turns out it lowkey has an super neat story so i stuck around for a few days exploring the nooks and crannies and going on dates w the ppl.l i found funny/cute then when i was done turns out i cant 'purge' a game from my account and sadly if anyone is using my laptop they could see i was playing a porn game and out here fucking dudes and a trans person...🫣
