This mod is derived from the old Control Surface Toggle mod. original thread is here: https://forum.kerbalspaceprogram.com/index.php?/topic/164626-*
Immersion gets shattered when you are in space and your control surfaces flap uselessly while maneuvering. Also, it's quite funny when you are on a planet with an SSTO which has airbrakes, and the airbrakes open when you hit the brakes.
What really annoys me is the useless engine gimbaling when I'm just rotating the vessel, etc.
