The relation walk and the bar at the bottom
How far Explorer follows relations from what is selected, and what the status bar says about it.
The walk
While records are selected, Explorer walks their relations on the server, beyond the records loaded in the columns, up to the tenant's traversal depth (performance.graphTraversalDepth, 5 by default). Records reached this way are highlighted in the open columns, and a path can pass through records no column has loaded. The bar at the bottom says how deep the walk went and how many related records it reached. The walk stops at 300 records; when it does, the bar says so and paths through further records are not shown. Only the tenant's own records and links are walked, deleted records and ended links are left out, and the walk carries no field values.
