Hi! I made a small mod a while ago that allowed me to swap item for the most effective one when clicking on a block here. However, Minecraft's code changes a lot and I don't really have time to maintain it properly. I also don't know Java and OOP.

With the wide range of features your mod has, I thought it would be a good idea to have this feature integrated into it.

Here's the workflow I had :

• Swap to least effective but still working tool when clicking on a block or mob
  • Swap to most effective if holding Sprint key
  • Don't swap if holding Sneak key

I think the integration with Sprint/Sneak is an intuitive one; Sprint is to go fast despite the hunger cost and Sneak is to be careful to not fall a cliff.

Other interesting settings :

• Swap to using hand if held item is enchanted and has 1 durability, but break it if sneak is held
• Use place block on farmland when breaking the above crop using this crop's seed
