I hope that functions are made in the spirit of ivy and helm so that I
can build completion based system for any choices, not only minibuffer
built-in choices.

For ivy, I have this:

ivy-completing-read is an autoloaded compiled Lisp function in
‘ivy.el’.

(ivy-completing-read PROMPT COLLECTION &optional PREDICATE
REQUIRE-MATCH INITIAL-INPUT HISTORY DEF INHERIT-INPUT-METHOD)

icomplete-vertical would be very useful function and I hope it will
get:

- full window support, like poping out of minibuffer to full window
- settable size of minibuffer
- actions like ivy with M-o or helm with TAB

Then I could develop on built-in Emacs features instead of asking for
too many outside packages to be loaded.

Let me know how to get that branch, that I can test it.
