Passive Nodes for try-outs

Feature Suggestion: Passive Mode for Nodes

I’d like to suggest a valuable feature for improving the Flowise workspace usability: the ability to set individual nodes into a "Passive Mode" (or similar toggle state).

💡 Problem
Currently, when I want to temporarily remove a node from the flow (for testing, debugging, or isolation purposes), the only option is to delete the node entirely, which results in the loss of all its configuration. Re-adding it requires redoing prompts, connections, and state logic — a time-consuming and error-prone task.

Additionally, if a node is present on the canvas but not connected to any other node, it should ideally not interfere with the execution of the workflow. However, in practice, these disconnected nodes can still affect performance or cause confusion.

✅ Proposed Solution
Introduce a Passive / Inactive toggle for each node.

When a node is set to Passive, it should:
Remain on the canvas with all its settings preserved.
Not participate in execution or evaluation.
Be visually grayed-out or marked as inactive for clarity.
This would greatly enhance development flexibility, enable A/B testing, and reduce unnecessary rebuild time in complex flows.
