Previously, it was only possible to inspect the data from the first iteration. That applied to both, the viewer node as well as socket inspection. Now, there is a new `Inspection Index` setting in the zone properties. It specifies which iteration should be used by the inspection features. In theory we could support features like counting the index from the end, but that can be done separately as well, as it likely requires more UI.
