➕ The default command can have a permission now. Just add a permission to the config key "settings.aec-command-permission". Default setting is still that this setting is empty and no permission is needed to execute the "/aec" command (excluding admin commands).
➕ Add a delay before a player can re-open the multi-mode inventory menu (settings.multi-inventory-open-delay | Default: 0)
➕ Add a delay before a player can re-open a chest (settings.chest-open-delay | Default: 0)

IMPORTANT: You may have to recreate your config before the settings appear. You can also see the latest config.yml in the documentation tab.
