With Unity Touch, tablet and smart phone users can easily browse, search, and open Windows applications and files, choose favorite applications and files, and switch between running applications, all without using the Start menu or Taskbar. You can configure a default list of favorite applications that appear in the Unity Touch sidebar.
You can disable or enable the Unity Touch feature after Horizon Agent is installed by configuring the Enable Unity Touch group policy setting in the Horizon Agent Configuration ADMX template file (vdm_agent.admx).
The VMware Horizon Client documents for iOS, Android, and Chrome OS devices provide more information about the end user features provided by Unity Touch. See https://docs.vmware.com/en/VMware-Horizon-Client/index.html.
