The Font Panel also is accessible from the Carbon port, via M-x
mac-font-panel-mode RET or Options -> Show/Hide -> Font Panel.  I
think making it global minor mode is a cleaner integration to Emacs
because it behaves as a non-modal floating panel just like the
Speedbar.

Though I have an implementation of the Color Picker from the Font
Panel, I didn't checked it in because I didn't think it much useful,
no counterparts found in other platforms, and there was a nasty bug in
the Carbon Color Picker that its window doesn't disappear in some
situation.

I'm asking the bases of your words, "after trying the Cocoa port, it's
actually much better than the Carbon port".  Without the concrete and
specific bases, you shouldn't have said so.

That might be good for a particular "distribution", but we are talking
about merging into Emacs core.  I would not add such a feature that
there are no counterparts in other platforms, unless it is too
Mac-specific.

Also, I'd give priority to implement fundamental features such as C-g
handling rather than fancy but superficial ones.  If you have been
watching the Carbon port in CVS, you'll notice that the proxy icons
and the font panels are added much later.  I don't know the current
status of the Cocoa port, but as of the last release, it still doesn't
handle C-g properly.

The importance of the GNUstep port doesn't affect the inclusion of the
Carbon+AppKit port to the later versions of *Emacs 22*.  Also, I've
been rather encouraging the merge of the Cocoa port to Emacs 23
(otherwise, I would still be working on the Carbon port for Emacs 23).

It'll be available after the Emacs 22.2 release, if its inclusion is
allowed.  If you want to see how it behaves, just test the Carbon
port.  They are pretty much the same except `deprecated' warnings :-p

And even with GUI, two major Apple apps, Finder and iTunes, are also
implemented as Carbon apps.
