:4 does not go to line 4.
Or at least, the line numbers are not correct.
No thanks, I'll pass.
I guess I can see the appeal; it's not for me though, I'm swimming in the local minimum of absolute line number dependence :)
I use relative numbers while in normal mode, and absolute numbers in insert mode. That way you get easy vertical jumps, but you still have a sense of your line numbers.
For maximum vimness you could let players mod an empty vinrc from start
The library seems great at the time, but I might need to look into alternatives in the future.
It sounds like allowing toggles for a few key options would probably satisfy most people while keeping the spirit of the exercise.
