Description of the feature request
Make defaults hidden by default from the “start screen”.
Use case / for what or how I would use it
Most of my workflows are supporting/reused for other workflows that would never be called on their own. Examples are “pre_build” and “post_build” or “post to slack” which are a way to share settings between other workflows.
When starting a new build, having all these options could confuse users and just clutter the list.
