+1

-reduce the "/butcher" risk
-makes repair shops efficient

Also as a side note, perhaps instead of this being in the extcommandsplus package it could be in the extcommandsplus2 package.

 

I could think of this being added for ++.
@Nicit6 Thoughts.

 

what if crepair was added for +
and crepair with a cpersist feature was added to ++

 

+1, but make sure you can't repair /cprivate chests, I don't need anyone walking around repairing every tool in my chests!
