Do you always bitch when somebody offers you an informative & educated opinion based on historical facts?
I think /hcopy is useless give that you can do it in a single command with /hadd already.
I think that /hrename would be quite useful, it an easy alias to script, however saving to file and reloading can become quite a significant waste of resouces/cpu cycles/etc and potentially slow a script down quite a bit. Much cleaner to just change one simple value in memory.
