NeoCrafts

Bulk crafting of sticks, chests, barrels, chains, cauldrons etc. in order to save time when crafting a lot of those items at once while keeping the cost per item the same.

You can now uncraft blocks like bricks, snow, quartz etc. back into their respective materials.

The mod adds the ability to smelt raw ore blocks directly into the smelted block variants, for example a block of raw iron into an iron block. This process awards the same amount of XP as if you smelted the items individually and only takes twice as long as smelting one item (20 seconds in a furnace and 10 seconds in a blast furnace per block)

This one is pretty self explanatory, just like how you can duplicate armor trims, you’re now able to duplicate pottery sherds using four bricks.

In recent updates, some previously uncraftable items like name tags and saddles were finally given recipes and this mod ports them to 1.21.1.

You can now repair an anvil in a crafting table, using 3 iron ingots per damaged tier (so 3 ingots to repair a chipped anvil and 6 ingots to repair a damaged anvil or 3 ingots to convert the damaged anvil into a chipped anvil)

You can now use only 3 iron ingots to craft 8 iron bars and 3 glass blocks to craft 8 glass panes (this does not include stained glass panes as you can already make 8 of those using a vanilla recipe)
