This should apply to all apps in general, but since Microsoft is so prominant in the IT world, my idea is targeted towards them. Many of the app controls, particularly settings, and frequently used controls are set up by default on the right side of the app. There should be a feature in the settings, or even while you are setting the app up initially after installing it, which allows you to switch the app's controls to make it easier for lefties to use. There may be only ten percent of us in the world, but we will continue to be a vocal minority in this recto-centric world. Thanks in advance!
