That was one of the bits I was missing. Makes life easier. Some bits are 
still  a bit of a drag though ( see later )

Found than now as well, but it would be nice if it obeyed the 
oneway=true :( Gets very cluttered otherwise.
It would be useful if the reverse segment function would reverse ways as 
well. It's a bit of a problem when you are adding stuff to existing half 
finished roads that were drawn from the other end.

OK - downloaded the latest version and have that working now.

That seems to be tied up with the direction changes. I found one of the 
segments was reversed, but perhaps THAT should have been corrected as well

I'm use to being able to modify things 'in-line'. A number of the little 
tidies that I have spent the lat couple of hous on would have been easy 
if I could just have fixed the record rather than having to delete 
things and add them back in. :( Actually what would be VERY useful would 
be a 'cloan' function for tags. Having tagged the main road, I could 
cloan those tags to the roundabout approach, add the oneway, and then 
cloan that to the other approaches that match. Anything to cut down typing.
