The plugin now provides feedback as indicators of successful progress.

1. Once the craftingtable is placed in the item frame on the dropper, the item frame will become invisible.
2. If you open the crafting block (dropper), the window will show the name of the recipe if the ingredients match a known recipe, otherwise it will show the name of the plugin.
3. Every time the crafting block crafts an item, the craftingtable item in the item frame will rotate once.

There is also now a cratmatic:show command that will show where all loaded crafting blocks are located and what their recipes are.
