To make the behavior consistent, may I suggest that you push the
concept even a bit further:
- add a "Load" *and* a "Save" buttons
- get rid of the top-level "Load an Alternate Configuration File"
and "Save an Alternate Configuration File" entries

For the "Save" and "Load" buttons, please mimick how the nconf frontend
behaves: prompt for the file to save to/load from, and prefill it with
the last filename that was entered (".config" per default).

Of course, two patches for that: one for the "Save/Load" buttons, one
to get rid of the top-level entries afterward.

Note: I do not state that your use-case is valid or not. That's your
call how you configure and test your kernel. However, I think that
having a consistent behavior across the frontends is a very nice goal
to pursue.

See other comments in-lined, below.

Space-damage. Don't send trailing-space fixes, or at least add a quick
note for it at the end of the commit log (eg.: "remove trailing space
while at it").

The re-ordering should be in a separate patch.
It makes it difficult to separate the code for the new feature from
the churn due to the re-ordering.
