Hey - this will hide the “Community Plugins” button AND the “Appearance” button (in settings):
.mod-settings.mod-sidebar-layout .vertical-tab-header-group-items > .vertical-tab-nav-item:last-child, .mod-settings.mod-sidebar-layout .vertical-tab-header-group-items > .vertical-tab-nav-item:nth-child(3) { display: none !important; }
