Clicking on the ABOUT MAIN in the scenario I’ve mentioned above just either expands or contracts the submenu pages in the navigation. I am using the sideout menu option in Mobile Header Options.
I’m not sure about that. Look at Foundation and Bootstrap, they both have a responsive solution to tables. Are you saying that the tables in your theme were not designed to be responsive?
Font Options and Font Size Options should be the same panel in the Theme Options panel. This is a huge oversight in my opinion and will yield better control over the typographic execution of designs.
