Running a form always outputs the UI to stdout:

This is problematic if a program ultimately produces some output to stdout that the user wants to redirect into a file or pipe into another program.

It would be awesome if there was a way exposed to change this to Stderr, or maybe it should just default to stderr like the spinner does:
