Hey Ramza! I found something!
In DQ11 Mode, when you only have 1 ingredient, you can still craft from the recipe list, with an recipe that uses 2 of the same items.

And maybe another quality of life feature would be, to let the cursor stay at the recipe position when you craft something. That would make it easier to craft multiple of the same items in DQ11 Mode!^^
have a nice day!
