We recommend to you to do all these changes in your Child Theme.
Now we have Placed New Option in Theme Options. So how to bring it to life.
Anywhere in your child theme just use this code to get the value:
jwOpt::get_option('my_awesomeness', 'SOME_DEFAULT_VALUE');
so we can use it e.g. by this way:
if(jwOpt::get_option('my_awesomeness', '0') == '1'){ //do sth }
