The answer has to be how the UI works (i.e., how I *interact* with the
completion mechanism and not how completions are computed.)

It would be wonderful if -

  All aspects of completion happens right within the mini-buffer.

With the default interface the following are turn-offs (which is pretty
much everything)

  - TAB, 
  - work window getting split in to two
  - Using mouse or RET for final choice

Since my bookmarks are function names, substring completion is what I
desire.  (Many functions share the *same* prefix)

[Context Switch] I think having a standard hook to choose the default
name of bookmark will also be useful.  In prog-modes, I will probably
set it to which-function.

May be there is a reason why completing-read-function is not
customizable?
