Maybe I have my settings wrong, or I don't understand how things are supposed to work, but it seems to me that the cursor for Painter's Eraser Tool should NOT disappear when it is being used to make a mark disappear.
If I put a line down and then want to erase it, I would like to see exactly where my cursor is WHILE DOING THE ERASING. Is there some good reason why the cursor disappears when we are using this important tool?
You can do this. Go to Edit/Preferences/Brush Cursor and put the cursor type on "Enhanced Brush Ghost" and uncheck "Show Icon When Painting."
