Hey @barn4k,

We have created an internal ticket to look into this which we will be tracking as "GHC-493"

Hey @barn4k , thanks a lot for the example! It proved really helpful when debugging my changes here.

I also found a workaround for until my fix is merged and released:

1. Switch to the Table view from any other node.
2. Reopen the node you'd like to debug
3. Switch to the false branch in the InputPanel there

From here you can use the other views as expected until you close the NodeDetailsView. Note you can use most features like dragging from the Table view as well.

heh, nice workaround. But it's easier to place a NoOp node right before the code node :)
