You can set up signs if you don't want players to access their VirtualPacks via commands.
Creating a sign
You need the vpack.admin.createsign permission. Simply place a sign with:
Line 1: [VirtualPack] or [VPack] (case insensitive)
Line 2: Arguments.
Using a sign
You need the vpack.sign.<tool> permission, where <tool> is the name of the component to be allowed (e.g. "chest" or "uncrafter").
Simply right-click a VirtualPack sign.
