Obviously 1 would be a major degradation of your excellent work. Alas, 2 doesn’t work for me, because the highlighter gets into the residue of white-out my mother left on the screen and makes it even harder to see what I’m looking at. And 3 is just too much work.
And it was your wife’s comment in panel 4 that I wanted to highlight. There’s that initial flash of, “Yes, that’s brilliant!” followed by “Wait…” Which you then capture in panel 5.
