I use kits for only the bots on my server.  Is there a way to disable even a blank kit menu popping up when someone types /kit in chat?  I mean, it's going to be empty, but I'd rather this not pop up at all.

simple edit the main .cs for the plugin and change the command to something no one but you knows.

Open the main .cs file you download from here using Notepad++ 

In notepad++ click the Binocular icon to search for keywords.
Do a search for: chat or kits or prefix

And you will find the kits chat command the plugin uses.
Edit it to whatever you want, and now unless they know what you put they cannot run the command to open it or use it.
