Hi @Anna_Trent, welcome to the Asana Community Forum and thanks for your feedback! It’s currently not possible to see all projects or tasks assigned to you across different Organizations in one place within Asana. You can upvote for this request here: How to contact our Support Team ✉
In the meantime, you can try using the Taco and Asana integration: Taco + Asana integration: prioritize all your tasks • Asana
Hope this helps!
