I really like this take on a different crafting system. Gone is the default crafting grid, a cargo cult reimplementation of one of Minecraft's worst features that requires you to memorise recipes or look them up in the recipes book. It has been replaced with a selection of crafting options you can search through and select, and pressing on a button brings up the different recipes to pick between (if applicable) and the ability to craft either just one or many in bulk.
What I especially like about this is that it hooks into the regular minetest.register_craft function and reads all the regular crafting recipes that get registered, so this could be used as a drop-in replacement that is compatible with all mods that use the regular Minetest crafting system. And of course it can also be dropped in as part of a game without having to change existing crafting recipes, which is what I'm personally using it for.
