Selected item color and potentially selected the same color, cause confusion when selecting groups of widgets

I have found that many times when I am selecting groups of widgets it becomes unclear what is sleeted and what I am hovering over. If the hover (selection target) was a different color than what I have already selected when shift-clicking to gather widgets into a group that would be really helpful. I find that I sometimes loose track of what I selected with a click and have to start over.

Yep, I too have the same issue.
