Comprehensive: Synchronize the following player data across-server. All of them can be turned on or off:
Inventories (& armor, off hand, selected slot)
Experience points & levels
Health (& Max health, health scale)
Hunger (& Saturation, exhaustion)
Statistics (ESC → Statistics menu)
Location (& Flight status)
Seamless: Data is centrally cached and distributed on demand via Redis messaging rather than constantly being queried from a database; this means the plugin is able to synchronize data seamlessly - players should have their data updated near-instantaneously.
Offline Viewing: View and edit the contents of player inventories and ender chests while they are offline.
