Installs the command "Pin Points" in the Constrain menu on the right. It freezes/pins the selected subcomponents. Then they can't be moved until the command is called again.
There's a displayInfo in the viewport that 1. lets you know something is frozen / 2. lets you set a falloff so points near the freeze region are a little frozen as well which makes the transition smoother / 3. set smoothness / 4. show or hide the blueish effect of the frozen region in the viewport
let me know if there's bugs!
