Okay, to be sure it is not the identical WordPress.org version of Gutenberg with its almost stray- dog selection of blocks as seen below:
But clearly the new WordPress.com editor has the look and feel of Gutenberg. As you can see in the screenshot below the new WordPress.com editor has a lot of features and design layout similar to Gutenberg:
Specifically, the new WP.com Visual Editor uses the same title field, top taskbar style, and a Content Editor block that reflects much of the previous Visual Editor functionality. However, the sidebar has a vertical accordion toggle straight out of Gutenberg [or vice versa – who knows which came first].
But what is fascinating is the new Media tool in the block’s +Add pulldown. Media handling now is really supercharged as seen in the screenshot:
These improvement in how galleries of images can be displayed is a big step-up over the traditional Media tool in WordPress.
So there are signs that Gutenberg ideas get tried and tested at WordPress.com in its new Visual Editor. So once again, WordPress.com resumes its role as a test arena for WordPress.
