It removes all the elements from VR hangar which are normally loaded in game and remains persistent all the time.
This is the seperate hangar file only from winghunter's mod

Summary is descriptive enough. It just removes the current elements in VR hangar. What's left is just the menu in almost pitch black background. In my opinion it even looks better than the hangar :)
File is ready for mod managers normally.
