Have you ever seen the tabs on that device? Do they show with a different theme?
I’ve not looked into it, but my mobile device is just a phone so I don’t have the real estate for wanting to see the tabs.
But I did try it some times ago to have horizontally stacked tabs… it kind of worked, but it took up too much space for my liking. Still, that was on a mobile, not a tablet. I think it’s described in an older post, if my memory is correct.
