Why is this being added to your items? I mean; no other item in the entire game has a tooltip with the durability of the item, and for people running with Advanced Tooltips shown(F3 + H), this is just an unneccessary repetition. If you want to include it, I suggest you either hide it behind a "Must hold shift to display" or make it a configuration option so that people can enable/disable this particular "feature".

Attaching screenshot of how it looks with Advanced Tooltips shown:

The removal of these tooltips is also included in the pull request I have opened.

This is a good point and I agree.
