We've pushed out an update to Destinations (content buildid 1275656):

• Fixed an issue where skyboxes were not showing up
• Added two default skybox materials (photos taken by Will Christiansen for Valve)
• Sort / Filter selection is now saved across sessions
• Added ability to add or remove items to a favorites list (accessible from the item detail view)
• Added new sorts and filters for the content browser, including "Favorites," "Recent" (i.e. updated since you last played), and "Unplayed"
• Added icons for updated, new, and favorite items in the content browser
• Added new lobby view when in multiplayer
• Added ability to access HMD anchor entity in Lua scripts (e.g. GetHMDAnchor() )

We've also added a new tutorial for quickly converting a SteamVR 3D environment into a Destination. You can check that tutorial out here:
