Another attempt to create versatile mod for in-world crafting. This mod was created for modpack makers to expand possible crafting while in early game stages.
Place the first ingredient on any solid block to start crafting. Place another one above the first and so on. Shift-Right-Click with empty hand to attempt crafting. Right-Click with empty hand (or just left-click) to grab the topmost ingradient back to hotbar.
Maximum number of ingredients in sequence is 16. Also it is possible to specify which block exactly is needed for craft (block tags supported as well as special conditions "$solid" and "$nonsolid" for specifying any solid or non-solid block respectively).
Output can be Item, which drops in world. Like this:

Or block can be crafted and placed:

Or result block can replace crafting block:

Toss items in fluid in any order to get the result. Items are invulnerable when they are used in a recipe (can't be exploded or burned, only despawned).
Maximum number of ingredients is 6. Desired fluid should be specified.
Out can either be an Item:

Or a new Fluid:
