    system: Align submenu labels with parent
    
    All section titles use an icon, while all corresponding submenu items
    are plain-text. As a result, labels in submenus aren't aligned with
    the labels in the parent, which makes them harder to read and look
    unbalanced. Address this by adding additional whitespace to submenu
    items to account for the additional elements in the title.
