When left clicking on a stock symbol in Portfolio a long list of options will appear. Color would add a quick visual orientation if only to break up the monotony of having to read each one to get where one wants to go. Imagine most people use the Charting option frequently and coloring it would make it easier to find. Perhaps coloring another selection nearer the top of the chart would be good to. Then at a glance we would know which direction to go to get what we want.
