Button/Control Pad Scaling

I just moved to the iPad Mini as a dedicated remote and it would be a huge benefit to have the buttons and control pads have some scalability.

My remotes tend to be very limited - arrow pad and playback controls as well as volume only - so they don’t take up much real estate and I find that using the mini with one hand forces you to be very precise with your thumb tapping (to which I am apparently pretty bad at…).

If they could be offered in a few different sizes or scale to maximum height/width of the display - I would prefer the former.
