Hello! I just stared using GB after a year of using GP.
I noticed that the icon for the button block inside a button container block is the same as the icon for the button container block. I work with people who are new to WP and so I can see when things are confusing. The container and the button are two distinct things and so it doesn’t make sense that they have identical icons. The button block really should have just a single button. Then it would be more clear.
Thanks for such a great product!
