The Flow Builder canvas is now more compact, so you can see more of your flow without scrolling or zooming. Element cards now show the element type and API name in an info tooltip to reduce visual clutter. The End element is now an icon instead of a full card, making it clear there's nothing to configure.
Where: This change applies to Lightning Experience in Essentials, Professional, Enterprise, Performance, Unlimited, and Developer editions.
How: Open any flow in Flow Builder to see the denser canvas. To view an element's type, hover over the info icon on the element card.
