The lack of space is on purpose, to save screen real-estate, so it
indeed needs to be customizable.  But I don't have a strong opinion on
what the default value should be.

Not sure what "highlighting" refers to; if you mean to put the first
element in bold, then yes, that fine.

Selection of current head can be done with minibuffer-force-complete
(not bound to any key by default), tho it doesn't exit.  But it should be
easy to add a minibuffer-force-complete-and-exit.

To get you started the patch below adds a keymap to icomplete.

Cycling would also be useful and should similarly be easy to add (it
just needs to play around with (completion-all-sorted-completions) and
store it back via completion--cache-all-sorted-completions, like
minibuffer-force-complete does).

> I can prepare a patch for (1).

We're in feature freeze, so please wait a few weeks before sending
your patch.
