The Models, Sceneries and Styles views split your library into what your workspace generated and what it added from the Marketplace. Until now that split was decided by who was looking: an item added from the Marketplace by one team member could show up among your own generated items for a colleague, and the "Own styles" tab could appear empty even when the workspace had styles of its own.
The split now follows the workspace that owns the item, not the person viewing it. Anything your team generated stays in Generated and Selected, and anything added from the Marketplace stays in the Marketplace tab — the same way for every member of the workspace. The Marketplace tab is also available when viewing a client workspace in the administrative view, which previously collected everything in a single tab.
