I'm working through this video:
https://cgcookie.com/lessons/rough-sculpting
At the 4-minute mark, the instructor duplicates a brush. Unfortunately, the Blender interface has changed since the video was recorded. It doesn't appear possible to duplicate a brush.
Does anyone know how it's done in Blender 3.x?
(Note that I can change the settings of an existing brush to match what's done in the video, but I can't save it as a duplicate, which would be very handy.)
Found the answer.
Click on the "Active Tool and Workspace settings" tab (typically in the tabs under the outliner on the right side of the screen). Click "+" to duplicate the current brush.
