Then the answer I gave should serve for you as well. You quoted the answer in
its entirety (not needed), but did you read it?

FWIW, the other things are not rare. Completion is used throughout Emacs, not
just for `M-x', `C-x b', and `C-x C-f'.

If you don't believe me, just `grep' for `completing-read' in the `lisp'
directory and its subdirectories (*.el */*.el). In Emacs 22.3, that's over 500
calls, hardly any of which involve buffers. Do the same for `read-file-name' -
about half that many hits.

This doesn't imply much about relative usage, but it is an indication that such
"other things" are not rare in Emacs.

(This is the hammer => nail speaking again, IMO.)

I already answered this clearly and in detail.


Icicles is not Ido.  It is not trying to be Ido.
The Icicles UI is intentionally different from the Ido UI.
If you want the Ido UI, use Ido.

If you want Icicles, you can still get similar features and behavior as in Ido.
If you want exactly the Ido behavior for files and buffers, please use Ido.
