Hey,
just a quick note:
If you use dark mode all the icons are white by default.
If you use also the predefined white-color as theme-color for your host, then you cannot see if a filter is active or not.
Example: If theme-color is blue, then the filter-icon will be blue when a filter (like “favorites only”) is activated and white if deactivated. If theme-color is white, then the filter icon is always white.
This is obviously not a direct bug, however I was wondering why the “white” is a predefined color when it brings some negative side effects.
My solution: Just switch from white to another color
