Select By Attibutes dialog: highlight rows( selected level) with another color.

If we select a row (level) and then we select another row (without pressing CTRL button), then the result selection is just with one level in the list but the previous picked rows are also highlighted in a clear blue. That´s it a lot of confusing!!!

Clear blue and blue are practically the same.

Please, don´t highlight the previous picked rows or change the color instead.
