They should provide all the information of the NetDiagnostics tool details on the Internet. Or, it will be good if they could upload the configuration and monitoring feature detail videos on YouTube .

REST API should be supported from the UI. As of now, it is supported from the CLI .

They can improve on providing "help and navigation" for each feature available in the UI.

In next release, I would like to see the application level monitor supported in some way.
