I see it too. I wonder what they are going to do with all that gorgeous real estate!
I like how it is easier to see the historical runs for the automation. However, I do not like how I must now open a second window to see my tables, fields, and data when configuring the automation. I sent that feedback to support and hopefully Airtable will take that into consideration for any future changes.
I also miss being able to see data changes in the same window when I test the automation.
