I want to know if it is possible to show up the headings by default when open the document
Hello @leandro
I am checking if this option is available. I will provide a feedback once any news come up.
UPD: I was informed that currently there is no way to automatically open headings section on the left toolbar when editors starts. Based on this, we have registered an enhancement suggestion to implement a parameter that would allow that. Once this suggestion is implemented, I will let you know.
