I can describe it as a good handy script for choosing a certain modifier in all the scene - in any scene node - and turn it on and off easily,
i really searched for this specific script and i couldn't find it.
i use it alot myself as i work in animation to turn on and off "flex" modifier because when you grab the time slide back when its "ON" especially in a big scene it takes alot of time.
You can use it with any other modifier such as turbosmooth ,etc.
sadly the modifier name must be identical in all nodes to have this script work.
