Sentinel-1 TOPS sub-swath and burst outlines difficult to see over ice and snow

When splitting Sentinel-1 TOPS, it’s really difficult, or impossible, to see the sub-swath and burst outlines when the swath is entirely over a white surface (e.g. ice or snow). I know it’s possible to define target bursts without the preview, but it is more convenient to do so with the preview.

Perhaps a dynamic outline tone in contrast to the underlying terrain could help.
