Can you change the default smooth brush to smooth directional on start up??
Default brush is the Standard brush when you open ZBrush, unless you open a previously saved project, there is nothing to sculpt on(or smooth) 
i’m referring to the default smooth brush…not the standard brush…i would like to change it to smooth directional instead of the default smooth brush…when you hold shift.
You could make a macro button to stick in the UI, or backup(in case) and copy(modify),rename/replace the brush.
