Area strech distortion - size comparsion instead of difference from average

Currently in UV editor if we check Strech/Area option we can see how different uv's area is in comparsion to average face size.

When i'm UV unwraping object i often want to make some parts with larger UV and other with smaller (like face and rest of the body). But currently i can't tell right away if uv island is larger than average or smaller and i have to check or fint that piece on model.

I propose to change behavior of coloring sterch. Instead of marking how different is face from average i sugest to make for example blue for smaller than average, green for average , and for larger red.

Like that:
