McMMO Suggestion - Pleasured

Indeed I shall in simple steps....
When you type /McStats a bunch of skills are displayed.
Now if the player had mcmmo.skills.hide.stats.mining permission...
When they typed /McStats ALL the skills would show EXCEPT MINING
However the player CAN still gain Experience in Mining!

Now with the other Permission, you can Disable the Skill Notifications!
If the play has mcmmo.skills.hide.notifications.mining
When they leveled up, It WOULD NOT show 'You've just leveled in Mining (3)'

This is Perfect for PVP Servers as they Don't want players to see the Gathering Skills in /McStats
But then they CAN Gain Experience in Gathering Skills! So no XP Loss!

Also the NO XP GAIN Permission where the player/group can't gain Experience in certain skills...
If the player has mcmmo.skills.disable.mining
When they Mine, they wont receive any Experience in Mining

We can take this further by only Selecting Blocks...
If the player has mcmmo.skills.disable.mining.diamond
When the player/group Mines Coal and Iron, they will still get Experience
But when the player/group Mines Diamond, they Wont get any Expereience because the permission is Disabling Mining XP in Diamond.

[ANOTHER SUGGESTION]
All Players have Power Levels that show their Total Level.
Arcane XP shows the Players Total Experience. and Would be shown under Power Level when typed /McStats
