1. I create a server and i put the LuckPerms and Essentials. The default group or other groups have 0 permissions defined and in game i have access to 5 pages of commands.
   If i set to false i have access to command. Why is not set all permissions to false if is not defined ?
   With PermissionsEx i don't have defined permissions and in game i don't have access. It works correctly.

2. Maybe need to move 4 fommands:
   creategroup -> /lp group create
   deletegroup -> /lp group delete
   createtrack -> /lp track create
   deletetrack ->/lp track delete

3. Meybe skip the message "already has this permission!" if the current permission is true and i set to false.

Try setting apply-bukkit-default-permissions to false in the LP config.

I'm happy with the current layout. The sub commands nested behind /lp group are for making modifications to existing groups, not creating new ones.

Meybe skip the message "already has this permission!" if the current permission is true and i set to false.

This is intended behaviour. Changing it would break the API signature internally.
