There seems to be only a few Brushes that also work with the Mixer Brush tool or Eraser Tool.
(1) Is it possible to select an existing brush that is setup to work only with the Brush tool and then adjust the brush settings to cause it to work with the Mixer Brush Tool or with the Eraser also? (If so, what changes need to be made?)
(2) Is there a quick way to see the brushes that are unique to the Brush, Mixer Brush, or Eraser tools? (It's a chore to have to look for the Brush, Mixer Brush, etc. symbol to find a brush that works with a tool you are wanding to use.)
(3) Do you have any video/tutorial recommendations on this topic.
