Just tossing my 2 cents in as I'd like to see a user controlled deletion option also. I don't actually have tons of games, but I've kinda messed up my collection by trading and selling off a bunch of stuff and not keeping track of them, so I'm thinking it would be easier for myself to just wipe the slate and start from scratch. Would be handy to have that option rather than me having to go and delete 300 items individually lol
