Thank you for the feedback and trying it out!
1: To use the handles of the gizmo you have to do a light press with the trigger. We know it’s not perfect, but we want users not to select handles that are in or behind the object when they want to select the object itself. I hope that helps
2: This is because we put you in game mode when entering VR Editor. When you go into the terrain editing you are forced out of the game mode and the editor shows all the icons and lines for objects such as lights and collision boxes. At the end of the laser there is a light, so that is why that icon is showing up there.
