1. Is this request related to a challenge you're experiencing? Tell me about your story.

When working extensively in the Dify workflow editor (testing, checking logs, using Preview, etc.), it's easy to accidentally move, delete, or disconnect nodes.

It would be helpful to have a "Lock Canvas" feature that prevents unintended workflow changes, such as:

Moving nodes Deleting nodes Creating/removing connections

A simple lock/unlock toggle in the editor toolbar would help protect workflows during development and debugging, especially for larger flows.

This would improve UX and reduce accidental modifications that currently require manual recovery.
