Headings less variables

We are very happy about all new feature in v 1.2.2 in Easy social, maybe the best for us and the developers is less compiling option and minify, now the question:

To modify base fon family in body sinmple changes the file located in /media/com_easysocial/styles/variables.less , and the variable @sansFontFamily

But for headings ? we modify the variable @headingsFontFamily but doesn´t fit ok , of course we compiling agains all files and minify .

Thanks for alll.
