Open up for HelpMessage and Validation to be supported in Automation runbooks input parameters.
Ability to describe and validate required parameters in more detail, in the Test Pane. Instead of starting a runbook that will fail due to wrong inputs, users will have to correct these wrong typings before initiation of the runbook.
Thanks for this feedback! We will look into this.
I can't believe this very simple but helpful feature still hasn't been implemented, some 6 years on!!!!

This would be really useful in a number of scenarios, My primary use case is using Azure Automation to provide automation with a specific set of options. These are defined in a ValidateSet so normal PowerShell users can identify the options easily, when using Azure Automation the use has to consult the documentation.
