hey i tested your add-on and i really like it a lot, now i tried to take a theme for SMF responsive and paste the CSS and i must say it works but need to improve the code is still not good, for example the signatures don't stay visible as in the desktop but they are staggered and some things like the quotes need background colors but the important thing is that it is usable from mobile.  Why don't you integrate a responsive theme so that everyone can use it with a simple click?
