Not abilities I'd like to see, but abilities I'd like to see DISAPPEAR from the client are the 'Pave' and 'Camera' functions.
With the ability to pave roads directly from the WME client, I think the client pave ability has now outlived it's useful purpose and is just an annoyance to serious editors in general.
It seems like every Tom, Dick and Harry and possibly one or two others, are driving around with this 'feature' on full-time.
100's of cameras appear bunched on top of one another in places where speed traps frequently occur. There are even cameras in the middle of high density housing areas where walking fast is virtually impossible, let alone driving.
There are no intersections within 100 sea miles where most red-light cameras are plonked down, so either they do not physically exist or the Town Planning councils or the Traffic Departments are wasting plenty of my tax money on erecting the so-called cameras there.
If adding cameras is moved to WME where it belongs, there would be no need to confirm anything and no need to delete tons more. Users can log new cameras they want added as a normal UR.
I'd guesstimate that about 5-10% of my edit points are from deleting tons of useless red patches in the middle of nowhere, and 100's of cameras I know for a fact cannot logically exist in that location, whether I know the area or not.
