Tracking nutrient limits
Cronometer works great for tracking that you are getting the minimums for your nutrients, but the interface is really poor at tracking nutrients that you are trying to avoid getting too much of. I would like it it the trackers for each nutrient could be set to either minimum or maximum for showing percentages. It would be best if the tracker also displayed the progress bar differently for nutrients that are tracking maximums (perhaps a blue bar instead of gold). Any nutrient with a maximum but not a minimum set would default to tracking maximum and a checkbox for each nutrient on the targets page would allow users to track the maximum even if a minimum value is also provided (default to this on for sodium).
