In an effort to share the most recent design work for Gutenberg, I’m pinging designers to get their latest explorations and visuals to share them with anyone who reads these updates. I am hoping this provides more insight into the work as it is happening. If you have got something to add, please share it below!
The W
With the introduction of the fullscreen default mode in the block editor, @shaunandrews has been exploring interactions to help surface the admin menu.

The Block Inserter
The Block Inserter has also undergone some redesigns. Rather than a popover as you’re familiar with, it’s now a slideout from the left side. It also now includes the Block Patterns which used to be on the other side of the interface. It’s looking amazing!

Menu screen
One recent addition to the Gutenberg plugin is the introduction of the Navigation block in the Menu screen. This is a response to the outlined focus of Phase 2.
