Extend hide is not annotated in the log, and it probably should be (definitely should be – nothing harder that debugging an invisible network if it is not identified as such).

I suggest it should present it like this

RIGHT 5@extendedloop

RIGHT 7@extendedloop

BACK 5@extendedloop

HIDE RIGHT 6@extendedloop

Another example, hiding two legs.

Similarly, this one should be …

HIDE RIGHT 3@extendedloop

HIDE RIGHT 4@extendedloop

And spicing it up a bit, adding some vertical and specifying hide with just a single station.

Again, this one should be …

HIDE RIGHT 3@extendedloop

HIDE RIGHT 4@extendedloop

And just checking normal = right and reverse = left:  It does the first time, but that does not test the subtilty of these statements.

Using that syntax repeatedly (not shown here) does either propagate the preceding direction, or keep reversing the direction, as is indicated in the documentation.  So normal and reverse is working and logging perfectly.
