and the vanilla ones.

The mod has an editor menu where you can add a new boss. Additionally, by holding Alt and scrolling the mouse wheel, you can change the boss's position in the checklist.

You can create an addon using the files from config/boss_checklist/overlap/; details are on the wiki.

You can also send these files to me (on github or elsewhere), and I can add them to the mod.

• Client: You can enable or disable progression mode, search bar, and the open button in the pause menu. The file also allows you to disable in-game settings menu, animations, some gui elements and y offset of the open button.
• Server: You can disable statistics, saving the name of the boss killer and multithreading.

/boss_checklist set_defeated namespace:id true/false – a server command that allows you to mark bosses for all players in the world (new players will also have them marked.)
