Description

• Give user hints when something is not right in the recipe, as soon he mouse over the output slot

Example:

• No Feedback when Tool has not enough durability
• Or no secondary items left
  
• Possible Solution (color slots like in JEI OR "?" Symbol)
  
• Extra: Post Massage what is missing when player try to click on the output slot ("Missing Tool", "Missing Secondary Items")

Mechanic

• Only check the crafting grid, when its matches exactly ONE possible output, then
• • color tool slot when wrong tool is in there (e.g.wrong hammer) or a tool is missing
• • color all secondary slots that are not needed for this recipe (only when all slots are full), else only color the empty ones
• • same with fluid

End

• This would help the user to understand what he is missing without looking into the tooltips of the tools or in JEI a dozen times

There is also a lack of displaying the requirements for skill and stage, if you don’t have a skill for crafting, then you can’t create a thing, but this is not displayed in any way. In addition, you do not know what level is needed to unlock recipe.

I understand that for 1.12.2 this will no longer be added for sure?

This is unlikely to be implemented because Artisan Worktables is now in 1.16. The 1.12 version will still receive fixes, but will not be receiving any new features.
