In ZorinOS Lite imo its three: Appearance, Windows Manager & Zorin Appearance.
Sorry if I wasn't clear but yes, I'm mainly focusing on the user side. Perhaps stating application may be incorrect, and GUI may be the better term to use.
Also if I recall, ZorinOS Core does not comes with gnome tweaks. This makes Zorin-Appearance the only GUI to change themes, making changing themes a very clear way to do so, even though its just Zorin presets.
Yup, I feel choices do add confusions at times although in XFCE's case, having appearance & windows manager together may be a necessity instead, depending on the theme.
Maybe I have been focusing on the user's experience based on the defaults too much, I have no idea. But my philosophy is, choices adds confusions. Hence only the necessary choices should be exposed, and the others should be tucked under an advanced option.


So one never knows as I understand this is the most creative version.
