[RFE] Hide inputs from FlowCharts

[rsevilla87]

Please describe what you would like to see in this project

Automatic FlowChart generation based on mermaid is quite cool, the problem is that arcaflow-engine make the inputs part of that diagram, that makes the generated diagrams ugly and not very readable.

i.e:

flowchart TD

It would be nice to hide the inputs from the flow chart, or at least having an option to opt them out

That shouldn't be too hard to do. It may require modifications to the dag library. We have several higher priority tasks right now. If you want to learn more about the architecture, feel free to give it a try. If you need help, ask in forum-arca
