The crossing out line...

Yes. And I wish they'd make the links stand out more, too. A neon colour might work...

May only be a point or two, but it would make a difference and be stylistically better in my view.

Indeed. But it used to be slightly thicker and what was crossed out was still legible but the line was easier to see as well.

but you've got to be able to read what's been crossed out...
