The mod has an editor menu where you can add or edit a 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/override/; 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: progression mode, ignoring defeats without your participation, search bar, progress bar, statistics tab, health and armor display, animations, and the buttons (pause menu, inventory, editor) with their offsets. Most of these are available in the in-game settings; a few are file-only and meant for modpack makers.
• Server: statistics, saving the boss killer's name, and multithreading.

Then again, the bosses themselves can also be edited.
