I looked at this, I honestly don't see how this is different from 
icomplete/ido.  AFAICS you select a program name by typing its name.

Again, please try (setq completion-styles (cons 'flex completion-styles)). 
With this "foo bar" matches both "foo bar" and "bar foo" (and also "far 
boo", "boo far", ...).

The default settings for icomplete/ido have some "highlighting", but 
probably not the one you want.  For example the current match is in bold.

These two features are not part of icomplete/ido, indeed.  If you need 
them, use ivy or helm.  Or wait until someone finds the time and energy to 
implement them for icomplete/ido.  Or find the time and energy to 
implement them for icomplete/ido.
