Redefining widgets

Hello,

First of all thank you very much for this excellent theme.

I want to redifine the widgets behavior, I’m using the lastest font-awesome version and there is some HTML modification to made into the <i> css classes.

I’ve made a child theme in order to keep the upgrading process working.

Are you providing a hook or any other way that can allow me to redifine the widget’s PHP file ?

Thanks
