Custom widget (vertical widget) for SuperMag not exist

I have a suggestion for developing this theme SuperMag and SUperMag Pro. I think it applies to other themes too.
Currently, I can not add a big widget. I can not add a vertical widget because the theme only supports square-size widgets not vertical for AdSense. I think would be good to exist this thing to let people add vertical widget too for right side bar.
AdSense widget can adapt to everywebsite. But in SuperMag there is not an wiedget custom one. Or an option in which we choose the size of the widget and add it to the section we want. Example custom widget html 562×282. You got the idea
