On my Nokia when it is set at the smallest display, the app shows 8 devices at once and it's very usable, however, the rest of my phone apps and features end up too small. I like the 8 devices at once as most of us are used to the 1-8 device remote with the 9-16 switch option or the 1-4/5-8 pads.
I can get 6 devices on my main Nokia with the normal display.
