In this screenshot I've bookmarked a few verses in a list of say, a dozen verses. I can easily export these "marked verses" to a New reference list, and then export them as verse references out of Accordance. Very good.
However, what I don't see an option for is inverting the verses that are marked, so that I can specifically export the verses that I didn't mark.
This is important (and I used such a feature in the competition regularly) because I may be writing a comment and making a contrast between a certain subset of verses against another subset of verses. As I see it now, Accordance doesn't allow for this.
The competition had a handy feature which allowed one to invert the selection, so that what was marked became unmarked, and vice versa. That would be nice.
