Linkable header ΒΆ
Problem: The lack of ability to reference post from one thread to another is lacking.
Solution: Add HTML attribute called "ID" to every post element on Flarum.
Notice: However, Headings do not work that way. Adding ID attribute to any <h123456> heading won't make it linkable. So there must be other system made for Flarum, so that it would be possible to link to headings from other posts on the forum or even other websites outside of Flarum forum.

Above you can see The pilcrow at the end of the heading. Which is might be used as a logo for calling function to generate link to this part of the post.
I saw this somewhere, a long time ago. And I though that is needed. Either as an extension or a feature of Flarum.
