Checkboxes if you plan a day's food ahead of time
I've started entering in the evening what I plan to eat the next day. That way I can fill out the day will a complete plan, adjusting foods and amounts to stay within my calorie budget.
Since the time of entry is not of interest in that case, it would be nice to have an option for the Diary display that replaces the time of entry with a checkbox. I could then check foods as consumed to verify that I've eaten everything planned.
Planning the coming day's intake has been quite helpful.
