I like to see the memory warnings when using Safari be fixed in this beta 4.
I would like to see memory controlled a lot better with this and kinda skeptical as it's not mentioned anywhere in this release. Right now my MBP has turned into a pretty and expensive Netbook as I can't do much without RAM being consumed for no reason and Safari refreshing because of it. As of right now just having this tab open and typing out this response, used RAM is 6GB...what a joke.
