I have an idea that would make this mod even more useful. Create an advanced crafting block that has inventory for the purpose of specifying the pattern, and then it takes inventory from anyside that is not the output and if the required materials are present to make the item it produces it. 

This is likely what you have now minus the internal part for the pattern.

and while I was writing that, I thought of an even more advanced crafter. One that has multiple patterns in it, patterns that can be enabled or disabled and whichever pattern gets satisfied that's the one that gets built. So maybe it has a patterns for a laser gun, diamond pickaxe, tnt, and diamond glass stairs. As inventory arrives when said inventory matches any of those patterns the item is produced.

I see that problem with that, but maybe that is where another option to craft a core-dumper would come in handy. It's purpose being to check to see if the crafter is clogged, ie is the crafter looping through its patterns and is the crafter's inputs all with inventory, if both are true, it grabs the first item from each input and outputs them to it's own inventory.

here's to  hoping you get 200,000 downloads!
