The canvas now works with touch

The canvas was built for a mouse. It now handles touch directly. One finger drags the canvas, two fingers pinch and the zoom anchors on the midpoint between them, and a tap selects a node.

The tap has an eight pixel threshold, which is what separates a tap from the start of a drag. Below it you selected something. Above it you were panning, and the click a browser fires at the end of a drag is swallowed rather than selecting whatever your finger stopped over. A tap on empty canvas clears the selection, on touch only.

The selected node now always shows its controls. Collapse, add child and open chat used to appear on hover, and there is no hover on a phone. A second tap on an already-selected node opens it for editing, which is the same request a desktop double-click makes.

This covers the app canvas, published maps and embedded maps, so a map on a phone is pannable wherever it appears.
