Is there a way to have borders and decorations?

Is there a way to have borders like here:

And line numbers in previewer and have a borders between parenting directory and current directory?
I cannot find an information about this in wiki.

Thank you!

Also displaying binary files with xxd would be much preferable!

You can use bat program for that like:
lfrc:

set previewer ~/.config/lf/preview
set cleaner ~/.config/lf/cleaner

preview:

#!/bin/sh

case "$(file --dereference --brief --mime-type -- "$1")" in
	application/octet-stream) xxd "$1";;
	*) bat --color=always "$1";;
esac
