Autocomplete In Recipe Editor

Add a list of common ingredients (probably hundreds or thousands of items) and autocomplete using that list when entering fermentables, spices, yeast, etc.

Start by locating the recipe editor and tracing how fermentables, spices, and yeast are entered. Determine where the common-ingredient list would live and how autocomplete should cover those categories; done means the editor offers matching suggestions from that list for each named ingredient type.
