Hey there.
If I'm being honest, I sort of forgot about this request. But fret not, I just uploaded a new version that includes a mode switch and the fancy new DQ11 mode. DQ11 mode allows the player to put the same ingredient into each slot, as long as they have enough of that item to do so, and also blanks the quantity display, and prevents them from changing the quantity via the right arrow key. This supports independent items from ItemCore, as well as normal items and equipment.
You can download the new version from the store page, or from your library on itch.
