It would be nice if streamified had options to limit twitter stream activity to @mentions and/or retweets (or your tweets) and/or direct messages. Merging all tweets into the Google+ stream can be a little overwhelming and may not be the best solution for all end users.
Thanks for the suggestion! This is actually something we're working on with our major revamp of our API. We'll be rolling out these new features in the next 3-6 weeks on the iOS and browser extensions.
