In the CurseForge comments you said there was a /sort command. This seems to be missing on the server-side. Does this only work if the client has this installed? If so, I think this should be fairly easy to implement on only the server.

Ah yeah this was broken at some point, thanks for noticing. Fixed in 1.7.8

Can confirm both commands work when mod is installed to server, does not need to be installed for the client. Great work @kyrptonaught!
