Include Caption Data in Visual + Numerical View

I would like to have some information displayed in the Caption view also visible in the Visual + Numerical view.

I can work on a mockup, but here's the main stuff that would be helpful:

- Caption hex (or eventually decoded) data per line visible as text in the lower left-hand side of the frame, below the BRNG data
- The chronological history of the digital caption signal (the black and white lines visible at the top of the frame) either visible above the video raster, or a miniaturized view in the bottom left (below BRNG).
