Thank you for the initiative and contribution!

I'd like to keep the version in the headlines, see my proposed change.

Besides that I like this and would like to merge it!

I don't mind having the files in the table, but I'd prefer to still have the version in the headlines, too.

Suggested change

	<h2 id="{{ id }}">{{ params.title }} <a class="anchor" href="#{{ id }}" aria-label="Link to this section: {{ params.title }}"></a></h2>
	<h2 id="{{ id }}">{{ params.title }} {{% if params.packages[0].version %}}- {{ params.packages[0].version }}{{% endif %}}<a class="anchor" href="#{{ id }}" aria-label="Link to this section: {{ params.title }}"></a></h2>

What do you think?

In the past there have been multiple versions in LTS so putting the version number in the header of all sections is not always possible but I think I can easily solve that with a flag in the config. That will essentially restore the current format but still be flexible. I'll update the PR
