oatmeal, #Emacs As far as I'm concerned, the jury is still out on TopSpace, but the more I use it, the more I think it makes sense... esthetically though it looks better with line-numbers off.
"TopSpace is an Emacs minor mode that lets you display a buffer's first line in the center of a window instead of just at the top. This is done by automatically drawing an upper margin/padding above line 1 as you recenter and scroll it down."
