As you may know, Canonical has worked a lot at Unity 8, which is currently used by default only on Ubuntu Touch, which comes pre-installed on Bq Aquaris E5, Bq Aquaris E4.5 and Meizu MX4.
For now, Unity 8 is more advanced than the Unity version for Ubuntu desktop, but this does not mean that Canonical neglects it. Recently, the Ubuntu devs have announced that a new feature will be implemented soon, permitting the users to swipe through all the installed apps while in full-screen mode.
Canonical did not establish a timeline for its new feature.
