Looking for some constructive (or even non constructive lol) criticism. Ever since i started DIY, i have been looking for a inventory management system for my concentrates, Nic, PG and VG. I have installed the big few calc's like juice grinder, ejuicemeup etc, but they all felt so clunky. Jumping between different menu's to get stuff done and some steps dont make sense. So I'm taking the lockdown as a time to create one. I'm no coder, and basically running on what i taught myself, so this might never get finished lol. This is what I have so far, I decided the Mix and Recipe can share the some page, so the recipe page will be deleted. Steeping will have a calendar view with which liquids are done on which date. Steep days still needs to be added. Shopping List will show a list of items I need to buy, either manually entered by clicking shopping cart on the inventory page, or when the threshold in ml's get triggered while mixing. Calculators, I'm thinking of putting in a few random quick calc's, like adjusting a bottle's nic, PG/VG Ratio, quick calculate how much (bulk) liquid i can make with existing nic on han, etc. Dont mind the empty columns, label's, etc, they will be populated. Also on the recipe side, it will only show the number of ingredients and hide the "empty" ones. Flavours can be increased and decreased by the + - for a max of 10 ingredients The Random R110 is a place holder for the price of the bottle, still need to find a fitting place for it. The bottom bar, is like a status bar, where it says, recipe saved, mixed, etc.
