Correct.  NM only ever connects if you have connected at some point
previously.

Right, this has always been "dirty little secret," in that there's no
GUI way to add/delete networks easily.  Part of the problem with _that_
is that this is something that's historically been quite distribution
specific, and I have no idea how a tool to do this would integrate with
every distro.  In the end, we should just write one and see.

Right now, this is essentially the AP that: (a) can be seen in a scan,
and (b) has the highest timestamp, meaning you connected to it most
recently out of all the other access points in the scan list.

Right now, you can't.  Doesn't mean we shouldn't find some way of
working this in.

At least in this case, you've correctly perceived the behavior of NM.

Thanks,
