Hello! First post here! I've been using Cronometer to track my nutrition for about two or three months, and I've found it to be a very powerful tool. But, I think it would be useful for some users, including myself, if we were able to create custom nutrients. For example, I would love to be able to distinguish between K1 and K2. I would not at all mind going through the trouble of creating custom foods with the vitamin K2 content included so that I could track it at a glace like other nutrients. I think it would also be useful for people who take supplements that aren't typically considered nutrients. For example, I supplement with creatine, but I spread it out throughout the day. It would be useful to be able to track that so I don't lose track of my intake. I think this feature would seriously augment this app's utility as a general intake tracker. I can see athletes getting a lot out of this in particular.
