Feature request: highlight x lines above and y lines below, w/o treesitter

[hacker-DOM]

Hi there,

it would be great if there way a way to use this plugin w/o treesitter, just highlighting eg the current line. I am currently using limelight for that (see my config below), but I would like to use this plugin instead...

let g:limelight_bop = '^'
let g:limelight_eop = '$'
