The latest builds of Interface contain a new mechanism intended to ease the use of the application in a head mounted display: menus rendered inside the 3D view. This new menu view can be activated by tapping the ALT key.
This will enable users to access functionality via the menu that previously would have been otherwise inaccessible to HMD wearers. Of course right now quite a large number of the menu items still open dialogs that are not rendered inside the HMD, which will have to be addressed moving forward by moving more of the user interface into the in-app overlay. Currently only the address bar and login dialogs have been ported over in this fashion, but more components will follow. In time, users should hopefully be able to create and modify content, interact with the marketplace and alter user preferences without having to take off a headset or switch into non-VR mode.
Right now this menu is available regardless of whether you’re in an HMD or not, though it could move to an HMD only feature in the future.
