I think editing the whole YAML is not a good solution. You might break things if you do unintended modification. It might be a solution for a few people but it does not resolve the problem behind your pain with the editor.

What we should do instead is improving the user experience of the workflow editor. Here are some examples:

• Allow to select multiple nodes to move them at the same time
• Allow to copy & paste nodes by selecting them and using keyboard shortcuts
• Allow to duplicate nodes by selecting one and using a keyboard shortcut
• Implement a bulk-edit mode for classifier to allow adding multiple classes in one text field using a line break as separator
• Add an way to edit multiple nodes at once, if all selected nodes are the same type (e.g. Render the LLM node UI if I select 5 LLM nodes. If I make changes, e.g. change the model, the change will be applied to all selected nodes)
  • There could pop up a button in the corner of the editor If I have multiple nodes selected and all are of the same type. This button could open the node in a "shared edit mode" which allows to sync changes to all selected nodes
• Add a menu for bulk tasks when multiple nodes are selected (even if they are not the same type of node), for:
  • Editing the title of all selected nodes
  • Editing the description of all selected nodes
  • Deleting the nodes
  • Duplicating the nodes
• Add a "Variable Creator" node, which allows to define multiple variables to re-use values in the workflow (e.g. a system instruction that I can link in all LLM nodes, or a HTTP header which I need in multiple HTTP Request nodes)
  • We could do that with a code block but this is very slow
• Allow to re-order classes in the Question Classifier node
• Allow to group nodes, colorize groups and move them around (large workflows are really a pain to maintain and can become really messy)
