Optional visual (GUI) editor for workflows

[kraenhansen]

Is your feature request related to a problem? Please describe.

When I'm editing a complex workflow I often feel overwhelmed: It's not easy to see the bigger picture when editing the 25th step of the 8th job.

Describe the solution you'd like

I would love a visual editor for workflows:

• As a start simply collapsable header and accordions for each job.
• Jobs could have its name on the border of a card representing it
• Each step could have a fixed height and controls to expand properties (with) and environment variables passed.

Additional context

An extension (https://actionforge.dev/) for visually editing a workflow already exists, but this use a different format and dedicated runtime for the workflows and doesn't operate on the standard workflow syntax.
