I'm getting the focus issue as well (I get it sometimes with the old extension, but much more with this new one).
Also, there seems to be no notification at all when someone messages you. That makes it fairly useless as an IM app. At least it doesn't pop a full conversation up in front of you like the old extension did.
It also doesn't seem to support multiple accounts (the old one didn't, either).
