Feature description

Please allow users to customise the colours of the overflow menu to match their theme.
Ideally, its background and text colours should automatically adapt to the active theme, or be independently customisable.

Why do you want this feature?

As shown in the attached screenshot, when a custom theme is created through the app's theme customisation feature instead of using a built-in theme, the overflow menu falls back to a black background, creating a visually inconsistent and distracting appearance.

This issue appears to be present across the entire app series.
