Idea for a new simple transformer (or extension to the AttributeFilter):
Like the AttributFilter but for Parameters
While it's easy enough to set up a TestFilter it does take a little bit of time to configure sometimes. Having a ParameterFilter which can automatically check for allowed values (e.g., if using the 'Choice' type) and just create the output ports would be nice.
Simply pick your parameter form a drop down list then enter values in the same way as an AttributeFilter OR click a button to import values (if the ParameterType supports it)
