Recipe Editor

I would love to be able to select and revise a recipe from the catalog then have a scan option next to the ingredients. That way you can accurately track the nutrition from the brands you are using. Also, be able to remove or add ingredients (I frequently I have to remove onions from the recipes so my family will eat it too or I add some bacon for extra protein/fats). If you edit a recipe in these ways having the ability to save to your favorites for frequent use as an edited recipe would be awesome. 

I know now you can edit nutrients but adding all of that up from several different ingredients is awful.
