That's a welcome development albeit late, but more importantly, they should address the "can't link to a highlight" problem on mobile. When all sections are collapsed by default, browser won't scroll to the relevant section.

A random "link to highlight" example: https://en.wikipedia.org/wiki/Henry_I_of_Cyprus#:~:text=On%2...

Such a link doesn't work on mobile if it points inside a collapsed section.

That makes directing people to relevant content on mobile really hard, and I end up sending screenshots instead.

EDIT: "Link to fragment"s had the same problem, but apparently, they fixed it. Thanks for that too!

The link in your comment works perfectly fine for me in Chrome Android, and highlights the part

You also can't search for text in collapsed sections.
