To summurize this plugin can edit furnaces, tools and weapons stats, names and desctiptions, also make them spawn in loot boxes like other items.
It can for example create different types of axes with different skins and gatherting rates.

Tried to find the name but no clue, maybe private, if someone can help me I'll be glad, if you think you can create one let me know.

names and desctiptions

You can't change item description, only item name. Also you can't use colors in names anymore, just text
