I was thinking about the different way to work function of Snapping + transform + pivot center!
would this be able to use the new UCS mode ?

like if you are in new UCS would the global mode follow the new UCS or the old one ?
Same idea when you work in Transform orientations Edge or face mode
would it be able to use the New UCS or the old one only ?

thanks
happy bl
