@dnp_theme thank you,
i’m about finishing the theme,
Your block headings are to blame for creating the illusion of bad spacing. My eye is trained to see that in fact the spacing is good despite the block titles background color.
i tried to create something new with the block titles style, but the user still can customize it’s size with the line height option in the theme settings, in the future updates i will add a new style option so the user will be able to select another style for block titles
i think the submission time has come. 
again, Thank you very much for your feedback
