Given the document
A B C
and with A selected in outline mode, currently the visual is that A is selected and B is not, which is a bit misleading since any edit you make will apply to B, too.
I think it would be better if row B were dimly selected, maybe a 50% blend between the selection color and the unselected color, so that one can tell both that B is included in the selection and A is the primary selection.
It’s not a big deal in tiny documents, but in larger ones it’d be nice to have a more clear visual indication of what range of the document you’re working with.
