Are more people with the default edit.js having the problem that you cannot cam around anymore after going into edit mode and pressing the ‘F’ key. Camming a round the object you have selected is now terrible hard or you could say impossible todo.
Lucky you can solve it for now with a workaround by using the cursor keys for left / right and zoom in / zoom out. hold shift and press up and down tilt the camera.
But this way does not make it more easy to build. And building where never easy already.
