[NB] RC9 Bug- changing multiple binder section types at once

If I select multiple folders or multiple documents in the Binder, then use the Inspector to change the section type, only the top item selected gets changed. All the rest do not change.

This is by design, in that the inspector only ever shows metadata for a single item; thus, the changes made there can only affect that specific item. You can use the right-click context menu in the binder, outliner, or corkboard (or the “…” button menu in the binder or editor footer) to change data for a multiple selection.
