Hi Jaco, this is really a reasonable thing to want, but to be honest, GNU Radio's visualizations are very much oriented along the streaming nature of GNU Radio – and scrollback doesn't fit all to well.
I recommend https://github.com/miek/inspectrum , which is relatively new, and relatively cool :) Other than that, there was a quite interesting email thread about this in 2014 [1] with scores of ideas and tool recommendations!
