Available Dates
Look for the next empty day log by chronological order from a time range where you likely never logged. Then add your meal plan to that day so it can serve as a template to refer to and duplicate to today's day log (Quick Tools -> Copy to today). You can also bookmark these dates so you can easily refer to and duplicate to today. To save a meal to an empty day log, you may want to save today's as a meal, such as "Temp", then add that meal "Temp" at the empty date log. This allows for much more flexible meal planning where you can just duplicate any variation of meal plans to today. You can tick the checkbox when a log has been filled in so next time you can see from this list, but you must fill these logs consecutively because I made the checkboxes only save consecutively to enforce proper usage so dates are not missed inbetween.
