on long report files, hard to filter to 'only uncovered lines' or such.

Try finding the 15 missing blocks here :)

Straw implementation suggestion:

1. linenos 'p' get 'covered' or 'uncovered' as per their line.
2. each of the header items become filter buttons to 'just show those' .

It's not perfect, but it might suggest what the right answer is.
