Copy a W&B saved-view  template across projects

A developer created a Python script that copies a Weights & Biases saved-view template from one project's workspace to another, preserving all sections, panels, workspace settings, and runset configurations. The tool reads the source saved view via its URL, reconstructs an identical workspace in the destination project, and automatically bootstraps the destination project with a placeholder run if it doesn't already exist. The script uses the wandb-workspaces SDK and requires only the source URL, destination entity and project, and a new view name as inputs.
