It's hard to tell at a glance what's a toggle and what's a drop-down with more options, it'd be useful if they were more distinct to be "this is another menu" at a glance

Eg; Verbose Mode Settings under HUD in User Interface does not look like it contains extra menu options at a quick glance. For an example of a possible fix, I've made a quick and dirty recolour to match the menu headings to try and make it consistent at a glance that "This is another menu"
