Add az/el bearing indicators along time axis of waterfall and audio plots
It would be valuable to plot specific az and el antenna bearings (and/or sat coordinates) on the waterfall and audio plots along the time axis. Knowing these could point out terrestrial signal blockages (trees, buildings) and make them easier to avoid in antenna placement. It would also allow measurement of what each station's actual minimum elevation should be set to. Measuring and setting minimum elevation correctly could avoid fruitless low elevation passes and possible maximize capture of an entire pass.
