Custom layout based on device

Would be good to be able to have a custom layout based on your device eh. Single column for mobile, multiple for tablets and desktop etc.

I once asked in the Configuration forum and here’s a response:

HA should do that already, does it not work for you? :cat2:

Your screenshot shows a smartphone version. If I want to show two columns, I can have my tablet in landscape mode. In a 10" tablet, I want Home Assistant to show two columns in portrait mode and 3 columns in landscape mode.

So, how can I configure Home Assistant to only show one column in Nexus 7 in portrait mode?
