Bonus: Pin Boomerang
To optimize your productivity, we recommend pinning the Boomerang Task Pane. That way, you won't need to click every single time you need to access the task pane. To do so, open the Boomerang task pane and then click the Pin icon in the top right corner of the task pane. You can pin both the Compose task pane and the task pane in your inbox.
