I am fairly new to the site but have found that I need to keep a list of my flavours and the quantity I have left of each in a separate spreadsheet. I think it would be useful to have a feature where by you can click to make a recipe from your recipe list and that will then subtract the quantities from your flavour stash thus always having an up to date list of flavours and how much you have left. This could be built on to track running costs of mixes you have made and could be customised to send notifications when you are running low on flavours.
Not yet. I only use price and volume to calculate cost of mixes. Internally there is a field that gets deducted, but it will not work properly until I implement batch/inventory control
