Printing the recipe list to the console works adequately for items that don't have many recipes they are used in, but the console will overflow for the more widely used items.
This mod would benefit from popping up a gui window with the list when an item is dropped onto it. You could also have a setting the user could use to toggle between using the gui popup or printing to the console.
A gui window popup would also be easier to read, as the environment makes console printout hard to see sometimes. Also icons next to the recipes would help with quicker recognition.
