WW setting for temps and color

It would cool to have a setting or change the options for negetive and positive where at a specific temp (IE 40 or -10 and 100 or higher) to change the color of the icon to a user defined color. So if you pick high temp of 100 or higher the icon could be red, and temp of say 40 or lower it could be blue.

Its an awesome program, keep up the great work
