How to expand all sub tasks by default or at least is there a toggle switch?

Thank you for the introduction @Bastien_Siebman!
I created a bookmarklet to do it and I’m fine-tuning it.
I’m planning to write a comprehensive “introduction to Asana bookmarklets” topic and I’ll comment here once ready

Update in July 2022: I created Introduction to Asana bookmarklets to discuss more about bookmarklets and show more examples.
