I use some malts that are not in the fermentables drop down list. I will use many of them over and over again, so each time I need to enter the same values for that type of grain, to get more accurate calculations. Somewhat how we can do with the water profiles, the users can contribute items for everyone to use. Of course, letting everyone do this may result in a total mess, so one idea would be to allow adding "private" fermentables? Or have some kind of review process before making them available to everyone.
