UETOOL-332 - Collections 2.0 UETOOL-369 - Want nested collections with collapsing We now have version 2 collections which maintain a persistent GUID for each collection. Existing collections will be lazily updated to this version when they need to be re-saved. This GUID is used by child collections to keep track their parents, and the collections view (as well as the quick asset management) now show a tree of collections. Collections in the main collection view tree can be re-parented via drag and drop. Performing Content Browser searches against a given collection will also test to see if an object exists in child collections, and the asset view will now show you folder entries for child collections when viewing a parent (if folders are enabled in your Content Browser view settings).
