Are you missing the underline and justify text buttons in the WP-Admin Editor? Several users have noticed their disappearance and commented about it in the community forums.
You can still use keyboard shortcuts to perform the above actions. If you need a reminder, you can find them by clicking on the ? in the second row of toolbar buttons above the editing box. If you don’t see that second row, click on the Toolbar Toggle button at the far right of the first row of buttons.
While this change doesn’t affect those writing in the Calypso Editor, it’s an additional annoyance for users who favor writing in the WP-Admin Editor.
One caveat worth mentioning: Justifying text may cause issues in responsive-width themes when viewing on certain devices.
This gives me an opportunity to repeat a poll from a couple of years ago where you let us know which editor you are using. Let’s see if things have changed since then. This poll will close 1 week from today.
Other recent news is the collaboration between Google and WordPress.com which allows you to directly publish to your WordPress.com or Jetpack-connected site from Google Docs, including all the formatting, images and all. Have you tried it yet?
