Are there any user documentations on how the hashtag bar works? I.e. how placing hashtags at the end of a posts create an expandable bar at the end of the post and also how hashtags with certain characters like #å in #blåhaj will normalized to ascii and placed there.

The #JoinMastodon doc on https://docs.joinmastodon.org/user/posting/#hashtags doesn't mention this.

Hey guys. I tag you all with this list of hashtags I follow. For those who don't know, since an update last summer, mastodon allows us to use all our tags in a more elegant way 😉

Put all hashtags in a single line of tags at the end of the toot, after an empty line break.

Also please, don't just copy your content from other platform without formatting it...

If you're attempting to build an #ActivityPub note that will end up creating Mastodon's new #HashtagBar, "last line" is actually the last element of the content.

It must be wrapped in an element like a <span>, <div> or <p> and only contain <a hrefs>(?). In addition, the hrefs must have a # directly before the <a> or as the first character in each <a> tag.

Is this spelled out anywhere? Hope this helps someone.

<p>#<a href>TagName</a></p> or <div><a href>#TagName</a></div> works.

Struggling to understand use-case for the new #Mastodon #HashtagBar. That's the feature that selectively formats hashtags placed one or more blank lines from the end of your text and shifts them into the status info area of the post, where they're then formatted to visually resemble a flat-UI "button."

People seem to love it.

But what literally is the point? Is it just to make shit look pretty? it's giving a qualitatively & quantitatively different treatment to some tags w/ no account of why.
