Guys, simple but extremely proved comment.
Gutenberg is great and would be really powerful.
But.. what is killing it is its EXTREME MINIMALISM.
I have tried gutenberg with at least 20 clients, and they simply cannot find the functions where they want.
Then, when they open the buttons to choose something, again, what they want is hidden.

My suggestion, always present row, column and add block buttons would pump it to heaven
