Unfortunately, I'm used to the permissionex commands, and the fact that you changed the key commands is a bit annoying because I knew them by heart, and you made them even longer. I wouldn't dare switch to this plugin while the old one works just fine.

Plugin is extremely simple to use. Developer was responsive to issues and fixed them promptly. I hope it continues to receive support for future MC versions! Highly recommend to use for small community server setups.
