We have all been there. Driving or doing something with multiple hands you accidentally turn your phone at a slight angle and it rotates. Now you have to take your attention off of whatever else you are doing and turn the phone so that it rotates back the way you had intended. This can be quite annoying even if it is a "First World Pain". You could lock your orientation, but that requires you to search through the settings. OrientationLocker loads itself in a position on the screen which then allows you to lock your orientation each time the orientation changes. The app is still under development so it may not be perfect. Grab it out at the source link below.
