It would make a good complement to the SM command, and it would be easier to examine complex graphic effects such as the layered parallax in Shadow of the Beast for example. In fact I think the command must also be able to blank out individual playfields when you are in dual mode.

Another example is the scoreboard in Swiv which Yaqube asked about some weeks ago. I had never heard of the playfield priority bug on OCS and my first thought was that the scoreboard bitplane was used to mask away the bits in the underlying bitplanes to achieve color 16.

You will have to inspect the copper list, save the individual bitplanes to disk and write code to display them, and with a copper list that changes the bitplane pointers frequently this will be a real horror. With a BM complement all this would take a second.
