hi sara
a checkbox would have been good. so you could for tablet and mobile view respectively activate certain modules. disable. so it would be very flexible for responsive considerate. they could not even consider whether you could do this function.
as for example: in the normal view could be active in a module position, the horizontal menu switch to "module1". the modul1 would you turn off the tablet or mobile, but a Modul2 where you could more active for the tablet, the vertical menu.
So it would be very good, you could specify for each module position, whether it should be displayed in the PC / Tablet / Mobile view. By default, everything can be enabled.
