Currently, you cannot use custom names, but reference tree nodes via their \"index\" anchors: \"0-0\" would be the first child of the root node, \"0-1\" the second etc. This is not ideal, I've created a ticket to allow outputting anchors.

Is it possible to refer to a tree's node's position from outside of a tree? When I try cetz.tree.tree( // ... draw-node: (node, p) => { if node.content.text == "1" {circle((), radius: 0, name: "anchor_1")} else if node.content.text == "2" {circle((), radius: 0, name: "anchor_2")} } ) line("anchor_1", "anchor_2") I get Assertion failed: Unknown element 'anchor_1' in elements (). Motivation: I want to draw arrows between sibling nodes in a tree.
