This extension shows all Asana tasks assigned to you across all of your workspaces. As a bonus, you can mark a task as completed right from the extension.
Asana has long been my favorite personal management tool, but the inability to see a global view of "what do I have to do" was annoying. This extension aggregates all that you have to do (i.e. everything assigned to you) and shows it to you in a single window.
