In the academy you mention that the Whitelight theme is responsive (adapts to display platform).
The Canvas theme looks more flexible for design, but is it responsive?
BTW I have been working on my iPad but ground to a halt when trying to drag Categories under Menus. Have searched web for how to emulate mouse left and right click on iPad but no joy with the suggestions. Possible incompatibility between WordPress and iPad?
Work around is to log on to my PC and use a mouse!
