* "Scenes" now shows for each scene lists of all view layers, collections and objects contained in it. This is the place to see all collections and objects in the scene even if they are not used in any view layer. Objects are nested according to parenting here. * "Collections" now shows all collections in the view layer, and the objects in those collections. Objects are not nested by parenting, only collections since it would be too confusing if the children are in a different collection. * "Groups" is unchanged. * "View Layer" was removed, replaced by "Collections". Part of T54790.
