I understand the urge to save drive space, been there myself, but there’s no clean way to do it unfortunately. Keep your installs separate (drives for OS, but partition is fine for games).
How do you avoid “hoarding”?
I dont. Hard drives are increasingly cheap/large. I have to really dislike something to delete it. I have a fair amount of content that I don’t really plan on watching again, but someone I know might like it so i just leave it typically.
Currently borked on firefox as well. Youtube just implemented some new anti-adblock fuckery.
