During the "normal" editing I know the edited segment's number. I could useful to know it during a filtering as well.
Maybe it is possible to display it, as at the attached image.
Another feature - clicking the number will act as the go to the current segment link.
I second an implementation of the original segment number when filtering is enabled.
