We've enabled a Quick Access option. This makes it super fast to add a task without leaving the application you’re currently using so you can stay focused on your task at hand while quickly tracking things yet to be done. Access this menu by clicking on the icon in the macOS menubar or Windows Toolbar. You can add tasks, initiate sync, make the app full screen, or access the app preferences. For Mac users, you can also access this by right-clicking the icon in the Dock. 

See it in action here.

This feature is available in version 10.5.11 and later.
