The items folder of the plugin will be treated as a separate item management configuration file, just like the items folder of the MythicMobs plugin.
The format of each item configuration file in the items folder follows ItemFormat.
In ItemFormat, an item option has been added that can be used to deserialize items, so ItemFormat can now directly read items that you have previously saved.
The /shop saveItem command has been improved, and you can now add bukkit or itemformat at the end of the command to determine how we will save the item.
