Hi Lars,You can do this today. When you create your project make sure to
select that you want two top-level collections instead of one. That will
give you the ability to create phone collections and tablet collections
(put the same articles in each one), and then apply a different layout
to the phone collections vs. tablet collections.This is a bit clunky,
I'll admit, if your content is shared. However it will work and will let
you share content across the two platforms.Neil
