This looks quite useful to me.

Feature request: allow the user to select separate colors for the relative and absolute line numbers, and for the slash. So three separate colors in total. That would make it easier to read.

Another idea is to have relative line numbers on the left side of the screen, and absolute line numbers on the right (or vice-versa).

I would love to take feature requests, but it's honestly not maintained. Don't get me wrong, it wouldn't be hard to reintegrate it with the current release, but I believe the idea should be at least approximated with vimscripts rather than making someone build a custom vim release to support this feature alone. Plus, now :rnu sort-of mimics this functionality by showing the current line number on the 0th row, instead of '0'.

On a side note, to your second request of left-side/right-side splits for line numbers: my first experimentation was to do just that. Left side was rnu and right side was nu, but the way vim's buffers work out, it wasn't very practical. It also caused headaches for rtl text and so on if I remember correctly.
