Hello KNIME Community,
I’d like to request a new node type that would display values directly on the workflow canvas without requiring users to click into nodes to view results.
Use Case: When creating workflows with multiple GroupBy nodes to trace aggregate values throughout processing, I need to track and verify calculations at each step. Currently, this requires clicking into each node to view the output, which disrupts workflow development and makes it harder to spot issues quickly.
Proposed Solution: A “Display Node” or “Value Display Node” that:
-
Accepts a table with a single value (or small set of values), such as a GroupBy, as input
-
Shows the value(s) directly on the node in the workflow canvas
-
Updates automatically when executed
-
Could display:
-
Single numeric values (from GroupBy aggregations)
-
Row counts
-
Key metrics being calculated
-
Status indicators
-
Benefits:
-
Faster debugging and validation during workflow development
-
Better workflow documentation (showing key metrics at a glance)
-
Reduced need to click through multiple nodes during development
-
Makes workflows more self-documenting for team collaboration
Example Workflow:
Data → GroupBy (Sum) → [Display: $1,234,567] → GroupBy (Count) → [Display: 150 rows] → Output
Has anyone else found workarounds for this, or is there existing functionality I’m missing?
Thank you for considering this feature!
