Functions like is_wifi_connected(), sendkeys() in keyboard app, blah blah blah...
They all use switch_to_frame() in the beginning or in the end...

I am wondering if we should make is_wifi_connected(switch_back_app) or something?
In that case, it might be a little bit not that confusing when you do a "is_wifi_connected" and do a switch_to_frame(self.app.frame) later?
