Manual node positioning and saved layout in workflow editor
The redesigned workflow editor always auto-arranges paths and disables dragging, so manually arranged layouts (still stored on the workflow) are no longer shown. On large workflows (about 50 paths) the auto layout produces long crossing connectors and is hard to read. Request: let users drag paths and keep/restore a saved manual layout, or choose between auto and manual layout. Related to the request to switch back to the previous editor.
