It can. On Windows, QuillSpace follows the Windows setting until you pick light or dark in Settings; press Ctrl+T and choose System to follow Windows again. On Mac, set Appearance to System.

Does the page width change my exported files?

No. The width only changes how the page looks while you write. Exports keep their own layout.
