9 months ago tinymce can do this, but for whatever reason it's been neutered in publii and its config is not exposed and that's the real issue here as i see it - unfortunately the devs have decided that exposing the tiny options should be done as a plugin #1280
that said, justifying text can result in an ugly mess, especially on smaller devices, and so you might reconsider
So far, Publii allows you to select a left, center and right alignment in the post editor. Although it is not a common option, I have the habit of justifying the text of my posts because I deal with serious and often academic topics.
Could the Publii editor include a button to justify the inserted text without resorting to HTML?
