What I would like to see is the ability to configure the same activity as two (or more) different layouts. For instance, I'd like to create two different layouts for my Watch Roku activity. One would be portrait, and the other would be landscape. I could then choose, perhaps via the Setup menu or some other configuration, which layout to view for each mobile device. This would allow me to create a portrait layout with fewer objects for a smart phone, but a more detailed layout for my tablet.
