Why You Need This

How this feature boosts your daily productivity

Big diagrams used to be an exercise in scroll-wheel patience. Drag-to-pan lets you grab any empty patch of canvas and pull the view across the whole graph, the same way you'd pan a map. A small movement threshold means clicks on nodes and links still behave exactly the way you expect.
