What would be a GREAT addition would be the ability to put "0" in the fields for nicotine so that your recipe is for making concentrates, without a warning window popping up every time informing me that I have "0" in the nicotine fields. I most likely am not just diluting a nic liquid, but instead making a concentrate for future nic diluting.
