everything i got was from : https://www.pioneer2.net/community/threads/psobb-addon-plugin-lua-ui-addons.4543/
basically you have to install this first : https://github.com/HybridEidolon/psobbaddonplugin/releases/
then the rest of the addons that you want are on the first link. i only have boss hp and items that drop. There are a few other useful ones as well.
