different colours for direction of travel on the highlighted roads

[joshinils]

I think it would be beneficial if the highlighted roads (now in blue) would get another colour if only one track exists for them or only tracks in one direction.
that way one could easily see if the existing imagery is only available in one travel direction (for ways without oneway=yes).
Expanding on this, if very many sequences exist for a road it could get another colour indicating that it is very well covered. Another colour could show that it has not been covered lately, meaning the existing images are "old" (refering not to the upload date, but the exif timestamp of when the images were taken).
