Make the branching functionality more obvious when building questions, especially on the first question.
When designing questions, it should be obvious that branching is possible - this affects how questions are written. There should be some connection to it near the actual question creation. Either a direct option to branch from there, or a pointer to find the branching ability.
You have the option in the 3 dots.

Anonymous, there is a branching option. On the top-right hand corner you'll see three dots, click that and a drop-down menu will show. The top option is called Branching.
Your request implies there is already a branching option. But i don't see one.
