Today, VMware released User Environment Manager 9.5. The main new feature is to be able to download Configuration Templates directly from the console.
You can download User Environment Manager 9.5 from here
As noted in the release notes these Configuration Templates are pre-configured Flex configuration files that are available for many popular applications. A Configuration Template simplifies the initial setup of an application and helps persist the most common user settings for that application.
These Configuration Templates are downloaded from the VMware Marketplace and contain a large number (currently 216) Configuration Templates for third party applications.
Below some self-explaining screenshots of the process
For other Configurtion Templates which are not (yet) included in the VMware Marketplates you can visit uemtemplates.com and upload them manually into UEM.
