I loves me my gmail. Now the goog is testing out some new features, and allowing all users to participate. TechCrunch has a detailed rundown here, but all you really need to know is there is now a new tab on the settings bar, “Labs.” From here you can enable new beta features that will possibly become fully functional gmail features in the future (largely based on user response). New ExFeats^{® ™} (my nonsensical-sounding invented name for this that I just created here and now, beware my wrath Google) are expected to be added somewhat regularly.
