Portion sizes should allow type in numbers instead of pop-up drop-down menus; some items are already like this but they are few and far between.

"Cups" should also be a standard option for every item to allow folks who are visually oriented easy access to input quantities.

Maybe require the item to be "added" before you can edit quantities; the number of times I've gone through the cumbersome drop-down menus editing quantities (especially when I'm using fractions) only to not have it save because I forgot to then also click the "+" before moving on to the next item is maddening!

Include more raw food options in addition of pre-packaged/ branded foods. For instance, I should be able to add "chopped cucumber" or "sliced cucumber" that I cut up and put in a salad, without selecting a brand that has who knows what else in it.
