1) I generally use the web version more than the mobile version and would like to have the interface work where you only need to double click the the description line (breakfast, lunch, dinner etc) and have have the Add Food window open. Right now you can right click on it and select Add Food, double clicking the line would be a better user experience.
2) I would like to see a way to carry over items from the previous day. Maybe the right click menu could have a Copy Previous Day option. For example, for breakfast you had eggs, bacon, coffee etc. The next day you have the same thing. A simple right click Copy Previous Day could bring over whatever was in that specific topic from the previous day. It would also be a nicer user experience than the copy/paste from the previous day that I do now.
