Hi, thank you for your explanation.
I am willing to learn the new way, but it would be easier if there was a guide explaining how to “translate” old way of working to gutenberg.
In particular, I praise the avoidance of php, but deeply regret that I could not find how to do the simple things described in my initial post 🙂
I am using the default 2022, with the bird.
In previous versin of wordpress I couls set the favicon or link the menu to categories independently of the theme – it is good practice to decouple functionality (navigation) from presentation (theme)
