About This File
A very simple tool I made to edit the body scales of my followers.
It is simply a little wrapper around the tools provided by UIExtensions and RaceMenu which you thus need to be able to use the scalpel.
There is no way to find it ingame, just use the console or AddItemMenu to get it.
To use it just equip and strike your target, the menu should instantly pop up. Note that it will likely make people hostile as you hit them so only use it on people that wont care 
This is quick and dirty but extremely simple and thus should work with just about any mods setup.
