ModActions
This mod is designed to allow you to control your vessel entirely via action groups, no more having to right-click on parts and control things through the part menu.
This allows you to do such things as change the thrust limiter on all engines on your vessel via a single action group command.
In addition to many stock actions, you can also control several mods via action groups in this fashion.
