The improved navigation block is great and I really like the fact we can now choose different menu icons, I look forward to the day that we can use our own custom icons!

I’m a huge fan of the new spacing controls features of Gutenberg that allow us to add our own spacingSizes in theme.json. This results in some great block controls in the UI that make it easy to adjust block padding, margin and block spacing and generates several new css variables like this: –wp–preset–spacing–20, –wp–preset–spacing–30, –wp–preset–spacing–40 which is exactly like Mark Root-Wiley discusses in the WP Tavern Podcast #28. This is a great step forward in creating some CSS standards that can be used in themes and allow more control over spacing.
