[Feature Request]: Visual Workflow Debugger (Wire Breakpoints, Step Controls, Variable Inspector)

[herophil322]

Is there an existing feature request for this?

• I have searched the existing issues

What is your feature request?

Summary:

Suspend Job, Replay Previous Jobs and Test Selection each help with parts of workflow debugging,
but none let you pause mid-flow at an arbitrary point and inspect live data without pre-wiring
a Suspend node in a convenient way. I'd like to propose a first-class Interactive Workflow Debugger: breakpoints on
wires, simple step controls, and a live variable/JSON inspector, similar to an IDE debugger.

1. Breakpoints on Wires

   • Click a wire/solder point in the Workflow Editor to toggle a breakpoint (e.g. red dot).
   • In "Debug Mode", execution pauses right before the downstream node runs when a token
     crosses a breakpointed wire.

2. Step Controls

   • Next: run until the next breakpoint (or end, if none remain).
   • Continue: clear all breakpoints for this run and finish normally.
   • Abort: end the debug session immediately.

3. Variable & Context Inspector

   • Side panel showing live state while paused: prev (data), workflowData, workflow.params,
     job metadata etc.
   • Search/filter bar for large JSON payloads.
   • Watch expressions to pin specific keys (e.g. workflowData.xxx) and see how
     they change as execution steps forward.
   • Live Edit: Allow editing a pinned value directly in the inspector while paused, so the
     modified value is picked up by the downstream node on Next/Continue, useful for testing
     edge cases or fixing a bad value on the fly without restarting the whole workflow.

I have no visibility into the implementation effort or how deeply this would touch core
workflow-engine concepts, but I believe it would meaningfully improve the usability of the
Workflow Editor overall. Thanks for reading this far, it would be awesome to see something like this considered
for a future release :D.

Oh boy. This is both the greatest idea I've ever heard, and the most difficult to implement 😝

I'll absolutely add it to the list, but this may take me a little while 😉

Thank you!

Haha, yeah, had this idea in the shower 😂 No worries on the timeline, just glad it's on the radar. Thanks for considering it!
