We used to have log-block and the wooden pick for checking who destroyed certain blocks, I think it was specificly removed so the staff can do a thurough examination of the area to make sure there isn't any evidence being missed.
Allowing people to use /pl doesn't make NoobsCraft unique 'cause then people can use/copy the same plugins, this might not be the case, but possibly why it was removed.. I might be making too many accusations, but this is just my view on each of your suggestions
