In reply to Johnny.

@Johnny - Really? (shudder) - If Gutenberg ever becomes something like Oxygen, I may weep openly. I like Gutenberg how it is currently.

The current early UI / UX of Gutenberg and the WP Customizer while limited are better. Before you ask - Yes, I have (unfortunately) actually used Oxygen itself and recently too. It still sucks the air out of the room IMO. While none of these tools are fully baked yet, Oxygen has the furthest to go being WP User Community friendly.

It's like the design for Oxygen was inspired by some old Adobe Photoshop version and implemented worse. Adobe's UI designs are often terrible to begin with (a sentiment shared by many better at design than myself) so using it as model for anything is likely ill advised from the start.
