These are the three things I use quite often from the context menu of the 3D view (click on the right mouse button in the 3D window, see the screenshot): The dynamic highlighting of objects (names, coloring etc) is sometimes too much information I don't want to see (e.g. flickering of information) so I deactivate it. When everything gets lost in the 3D view due to a rotational move etc and I don't get it back, I reset the camera back to the default settings. The settings of the 3D view allow you to change the point and curve sizes, the background color and other things (e.g. this nice camera feature: use the same camera for multiple 3D views).Cheers Joerg
