Feature request: Colored HR / Power data fields

Not sure whether something like that has been requested before, but I would love to see the option to have heart rate and power data fields to show the intensity by changing the background color of the field to e.g. green, yellow, red, etc...

Now I know that for example with graphical fields you can have the heart rate number with the corresponding color in form of a circle around it. That's exactly what I'm suggesting, but please make this available as a small field as well. Just the number with a colored circle in a small field would be awesome. Otherwise, one loses 4 (small) data fields if you use the graphical versions of HR and power that way (which equals almost half the screen).
