This is cool stuff, thanks for sharing!  

== Text display ==
Not sure if this is helpful, but the only thing that occurs to me is
that it's not instantly clear which configuration sections have been
completed.  The screenshots show a "[ ]".  I understand that to be a
textual representation of a checkbox, but it seems hidden on the line.
My eye doesn't instantly draw to it.

Perhaps if it was more in a table format?

== forced ordering (*) ==

The asterisk (*) denotes sections which need to be completed first.  The
text-based hub concept seems to compete with having a required order for
steps.  Should the (*) steps that have a discrete order not be included
in the text hub?  For example, should the user be prompted for those
steps before presentation of the hub?  Or should we have 2 hubs
(Required configuration and Additional Configuration options)?

== Keypress for (Q)uit and (C)ontinue ==

Having quit and continue as numbered selections seems odd.  Would it
make more sense to have the keypress for (q)uit be 'q', and (c)ontinue
'c'?  This would keep documentation easier since the keypress would
never change.  Whereas, if the key for Quit is (9) in F18 ... it might
be (8) or (10) in another release?  Also, this aligns with my experience
with other text-base tools (like yum [Y/n]).

Hope that's helpful!

Thanks,
James
