When I set the border radius for Cards in our community Theme, it doesn’t apply to the quick links widget. Thus, I have to remember to adjust the radius every time. 

I’m sure there are versions of this for buttons and other widget features too. 

Keep: The ability to customize widget styling with border radius adjustments, button colors, background colors, etc. 

Add: When something is set as a default in the theme (border radius, etc), apply that default on applicable widgets as well.
