Have you ever driven a car where the manufacturer put everything (headlights, wiper blade speed, cruise control, etc.) on one control arm attached to the steering column? Talk about not having enough elbow room. I was experiencing the same thing with all of these gadgets running in the left-hand column of the Gmail interface; I was feeling claustrophobic.
Luckily, there is a Lab available in Gmail that will take the gadget with the biggest potential foot print, Google Chat, and move it to the right-hand side of the window: Right-side Chat. Labs are small add-ons to your Google Apps to enhance or add efficiency to your Google experience. You access these add-ons from the Labs tab in the Gmail settings window, or follow the Google Support article by clicking here.
