Categories (for wine and spirits, for example)

Got this up and running last night for a party at the weekend. It’s a great app! I appreciate that this isn’t the core reason behind the development of the app - with its focus on beer - but would it be possible to add additional categories for wine etc. It would be great if it could cycle through the beers and then show the next category before cycling back to the beers,and so on. At the moment, when adding other beverages they are mixed in with the beers. Thanks for looking.
