        setRootPanel(tabs);

        // Main Menu
        WGridPanel menu = new WGridPanel();
        menu.setSize(300,200);

        WLabel menuTitle = new WLabel(Text.translatable("gui.control_ui.menus.main.title"));

Also there are some pages in the documentation I can't access. It just shows red and clicking on it brings me back to the main page.

That is the background drawn by the default background painter used for all root panels in LibGui.

You can disable it by overriding GuiDescription.addPainters to do nothing.
