Yes, I can think of several things to do to make the list better, however the amount of time it takes to just add a few colors is more then I have right now. It took about 16 hours to gather and update the list just with the new additions. I have already solved the different recipe sizes with a convertor in the excel sheet download. It will up/down any recipe to any oz you want. And if you don't want to spend 5 bucks then grab the trusty pen and paper.
Keep the ideas coming though there is no telling if I will get to them someday.
