Improve Live View Info panel

I would like to see improved with tethered capture. In live view and in tether Tab, there is a panel called Live View Info which has Rotation and Pitch readout from the camera. Would it be possible to get more information and maybe not as jumpy?

With artwork repro, I must shoot artworks from vertical, horizontal and on many different angels. So, it would be great to have this information larger and have as much information as possible like Pan (yaw), rotation in both axis (Roll and Pitch). One situation, I have an artwork mounted at 11 degrees, I have this information in tethered live view I can dial in the geared tripod head to the 11 degrees without using another device to measure.

Having all of the data (Pan, Rotation and Pitch) will help ensuring the camera is parallel to the surface of the artworks when its not in a vertical or horizontal position.
