1. Is this request related to a challenge you're experiencing?

When debugging a newly created workflow, I have to re-enter the input every time. Debugging a single node also requires entering input variables repeatedly, and it needs to be adapted to consider the output of the previous node. Debugging efficiency is not high.

2. Describe the feature you'd like to see

Personally, I believe the following design can greatly facilitate debugging and exploration:

1. Save the input of each node from the last test run.
2. Can the testing of connected nodes be designed to run in a sequential cell debugging manner similar to Jupyter Notebook, where the next node can read variables from previous nodes?
3. Can a button be added to run from the start to the current test node?

3. How will this feature improve your workflow or experience?

Based on real-time node operation information, facilitate immersive design for current and next node input-output adaptation, as well as saving repetitive calls to LLM and other tool APIs.

4. Additional context or comments

Make debugging workflows as straightforward as debugging ipynb code~

5. Can you help us with this feature?
