One thing that I think would be great is a improved compositions.
I think it would be great if one could have 3 or 4 different composition groups for example Cocktails, Drinks Specials(eg. Doublr Rum), Shooters. The other thing is most Hardtack items will be in tots(25ml) and some cocktails and shooters use half and quater shots in there compositions. This would make stock control much easier.
