This is a suggestion I had a while ago, but it was kinda forgotten and lost in the dust, until now.
Often theres issues where inventories need to be checked, whether its after a gym battle, to check items were given back properly, an elite battle (checking for illegal items) or just general player disputes.
Permissions as such:
essentials.invsee
- Allows access to the /invsee command. Inventories aren't modifiable with this permission alone.
essentials.invsee.modify
- Allows players with /invsee to modify player inventories.
essentials.invsee.preventmodify
- Prevents that players inventory from being modified by others.
I'm only suggesting the basic permission, just for inventory checking reasons. Hope this is taken into consideration
