Admin Vault Viewer
/pvconfig view <player> <number> opens any player's vault directly in your GUI. The title shows whose vault you're viewing (e.g. Steve's Vault #3) so there's no confusion. Any changes you make are saved back to the vault owner. The target player does not need to be online — vaults are stored by UUID.

FAQ
Do vaults persist after a server restart?
Yes. All vault data is saved to world/data/private_vaults.dat and loaded on startup.
Can other players access my vaults?
No. Vaults are private to each player. Only server operators can view them via /pvconfig view.
What happens if a player's limit is lowered?
They can't open vaults above their new limit, but the items are safe. Raise the limit again and everything is still there.
Does the target player need to be online for /pvconfig view?
No. Vaults are stored by UUID so offline players' vaults are fully accessible to admins.
Is this server-side only?
Yes. Clients do not need the mod installed.
Does it work in singleplayer?
Yes.
