What is this add-on they use? It separates different forums in different categories. https://www.minemart.org/

@Twuaty_Ak look at the one I posted. Yeah it had branding and is unmaintained but you can still download and use it. I have used it in the past and actually may use it again. The only catch is if you use any variation of the UI.X theme uncheck collapsible nodes or the addon won't work. There is a post in the thread that tells you about it.
