Is it possible to change orientation in Preview Mode?
Not at present. I think it is needed.
Using local network preview on devices I found was more accurate. And you can get a better feel for user interactions. Local network has been my fav for a long time, it recently got some dev attention too.

Also most browsers have device emulation. Edge does a nice job of it too. Safari did, but it seems to have changed and not as good as it was
We did have Solis, but that seems dead in the water from early on.
Yeah this is a good idea to have this.
I still prefer to grab an iPad, phone and MacBook and doing in-depth final test that way!
But different orientation will be brilliant @Norm
Big overhaul on preview mode already in the works.
