I would like to sort my games by ELO so that I can work on those games where I am weakest. Is this possible to do right now?

I'm not aware of a direct BGA mechanism, but I'm pretty sure if you scroll to the bottom of your XP games list you'll find your lowest elo games there anyways. I don't think it's directly sorted that way, but there's a pretty big correlation between your lowest elo games and bottom of the list stuff. No observable rule has perfectly held up to me, but given it's the XP page I wonder if they rank the games by how much they've contributed to your XP total. I don't pay any attention to the XP count and don't know where those stats would be offhand, so I've never checked.
