The preview of alpha texture brushes needs improvement

I use alpha brushes to improve my model's look. I usually add dirt, rust, wet-looking, etc by using them as a mask. But whenever I want to add brush image, it always previews with a black background and I can't choose my brushes properly so I tweak it with color ramp (invert colors and make white transparent instead of black).

As the majority of brushes being black, I think a preview with a white background or tiled like alpha background that gimp like Softwares uses would be very nice in my opinion
