Select the node in your workspace.
Click the three vertical dots to open the dropdown menu.
From here, you can choose:
Hide: Temporarily makes the node invisible in the workspace. The node still exists and works—it's just hidden from view.
Disable: Turns the node off. It will not run or affect the model until you enable it again.

Learn More: Opens detailed information about the node, including what it does and how to use it.

Shortest List: When connecting lists, this option forces the node to process only up to the shortest list length.
Longest List: Processes data based on the longest list available; shorter lists repeat values to match.
Cross Reference: Combines all items from connected lists in every possible pairing (like a grid). Useful for generating multiple variations.
