This sounds awesome, really gives the menu a calmer look. Especially when you got a bunch of plugins that keep expanding the menu.
Maybe this gives it a kickstart, this css looks like a pretty good divider to me (on the entries item for example)

#nav-entries {
    border-bottom: 1px solid #999fa6;
    padding-bottom: 8px;
    margin-bottom: 8px;
}

@SayChi Yep, this will be coming in a larger overhaul of the plugin, for its next major version, which includes a lot more flexibility with groups, nesting, etc.
