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?
I think this may be subject to your cursor settings, but I do agree that it would be nice to at least have the option of a ghost, especially with custom dabs.
