I am using something I think is useful, you may or may not agree, but here goes:

I have a custom program I use most of the time. It uses the XY graphic. At the next highest program number I have the exact same program except it has the horseshoe graphic. Why do I do that?

1. In certain situations the VDI number is hard to read on the XY screen but on the horseshoe screen it's much larger.

2. I can immediately see what freq I am on (does not show on the XY screen).

3. I may have the second program set on a different freq to see if the VDI changes on the same target (can be useful IDing bottlecaps).

And I can just press one button (+ or -) to see those things,and one again to return.
