You can now transfer vanilla enderchest to EnderEX chest via the command /enderex transfer <player>

if you wanna force the transfer, even if the player already has items in his EnderEX chest, you can do /enderex transfer <player> force

The player HAS to be online for it to work.

Keep in mind, the transfer will always abort if the player has less than 3 rows in his EnderEX chest (so enderex.chest.3 permission minimum)

I also added an option to do it on player login, same limitations, it will not overwrite if the player already has items in his EnderEX Chest, but if you recently added the plugin and you need to migrate players chests, that's the automated way to do it.

New option : you can disable the physical replacement of enderchest in the options, if you disable it, the player will have access to his vanilla enderchest when he opens it, but will access the EnderEX chest when doing the command.
