As I said, `completion.el' is part of Emacs, and
has been for a very long time.  You don't need to
"install" it.  You don't even need to `require'
it.  Just turn on `dynamic-completion-mode'.

So maybe you're not acquainted with `dabbrev'
after all.  The `d' is for `dynamic'.  It uses,
as its base for completion, words you've already
typed.

`abbrev-mode' works off of a set of explicitly
defined abbrevs.  Dynamic abbreviation works off of
words you yourself use, automatically.

Emacs is a world.  A world has a lot to explore.
Don't get intimidated or overwhelmed.

If you want to propose improvements to Emacs,
then it kinda behooves you to be somewhat
acquainted with what already exists - the thing
to be improved.

Different people find different things to be faster
or more valuable.  I won't argue with you about
your preference.

And there are different kinds of "pop-up window",
and different means and triggers for popping up.
Those differences affect speed and convenience.

The set of completions popped up also affects
things: how many choices? what order? can you
change the number of choices? on the fly? can
you change the sort order? on the fly?

These things are not black & white ("_the_
most valuable").  There are advantages to
each possible combination, and different
people, in different use contexts, find
different choices to be most helpful/useful.

Even easier: `M-x dynamic-completion-mode'.
But to see the description you need to consult
the library's Commentary text.
