oRA_EasyPTs is a FuBar plugin that only shows up if you are using oRA_MainTankFrames . It allows you to quickly set your PTs by targeting them and adding them to a dropdown list with a click. Removing them or clearing the list is just as easy. The plugin disables its own functions when not in a raid.
