Version: 1.8.8 I would like a plugin that hides players from the chat and tab list if they are not in the same world. no commands or permissions
https://www.spigotmc.org/resources/tab-1-5-1-21-2.57806/ Check this plugin. It has per-world tablist support and is available for Version 1.8
My bad, I misread, didn't see you said chat https://www.spigotmc.org/resources/✅-worldserver-▶-per-world-chat-tab-and-eco.99010/ This plugin exists but it does not seem to support 1.8. Coulnd't find anything else, sorry
