Fold-able meals display

Please make the "Breakfast", "Lunch" and "Dinner" of the My Day page being fold-able.

At lunch time, the "Breakfast" may be folded by default, that will save a lot of scrolling time. 

At dinner  time, if the "Breakfast" and "Lunch" are both folded, it save even more time.

With current design, I have to scroll a very long list of foods back and forth in order to see the change of the pie and bar charts as a result of adding one food to dinner.
