With the latest release of WordPress 4.7, the default wordpress editor buttons for aligning text justify and the text underline feature are now missing. The main reason for the removal of buttons is quite simple, they say that it renders inconsistently in different browsers. I do believe that it should not be removed, although they have that reasoning. I mean it has been there since the beginning of time.
Anyway, there is nothing more we can do about it as of the momment, the only thing that we can do is to find another solution. And the solution is rather easy to implement.
Actually, since WordPress is using Tiny MCE as the default editor, the function itself was not removed, it was hidden on purpose on this wordpress release. So what we can do is simply show it again or just invoke a keyboard shortcut to use the same functions again.
Here’s a quick video for easy implementation.
Let me know your thoughts.
