Properties menuVia Edit/Properties a user can open the Properties menu on the right of the window.
This menu allows to fine-adjust reports.
Is there further documentation about the Properties Menu?
E.g. the tree structure on the top, what does it represent?
Is there a search function like the xpath functionality for the Display Tree?

Automation and ScriptingRe: Properties menuProbably you know this already, but my response was triggered by "tree structure". Besides properties, it is also possible to view the tree structure of a report by right-clicking into the topmost disclosure icon (the grey triangle lying on one of its catheti) > selecting Edit -> Show Tree Structure.

Per "Jump into JMP Scripting"; which summarizes all I know about the tree structure; this is for finding the different display boxes in a report so these can be adequately referenced.
From the book:
JMP draws a diagram showing the hierarchical organization of the different display boxes that make up the report. ... These are basic display boxes found in most reports, and there is a number associated with each one. Knowing the type and number of the display box enables you to reference individual display boxes in a JMP report.
