Change color of taskbar icon when - stop all traffic - is egaged

Taskbar icon needs to change color or a bar goes across comodo icon when, “stop all traffic” engaged.

My memory is for s__t, on more than one occasion have stopped all traffic only to forget I did it, and then

spend the next hour trying to figure out what is wrong with my internet connection.

Previous program I used, had that feature, I miss it !!!
