In-game colletions menu
We have a plugin that adds custom items to the server related to Hololive vtubers, their effects range from weapons to movement items to items made to annoy other people. Some of these items require collection “points” to be crafted that can be acquired by doing different actions in-game, like killing mobs or using items, you can check all the items and points needed typing /collections in the chat.
In the in-game collections menu you can check items in a collection and points necessary for them by left clicking one of the heads. You can check what action is needed to get points in a collection as well as how many points you already have by right clicking one of the heads.
You can also test these custom items in Creative world by doing /acquire <item>
You can find the plugin source code here.
