Emacs display inline suggestions

Question

My Emacs configuration used to have a functionality where if I would call, for instance, M-x or find-file it would display inline suggestions as:

M-x [ align-regexp | auto-fill-mode | ... ]

But when I updated the Prelude the other day, this functionality disappeared. To my shame, I have to admit I don't know what this functionality is called, or how to reactivate it.

I'm running Emacs24 with the Emacs Prelude.

I'm Prelude's author. The functionality you describe comes from the smex package, that's enabled in prelude-ido.el. Some time ago ido support was moved out of the default configuration into a separate module (so people that don't use ido and its related packages could disable it easily) and I guess that's what's causing your problem. You probably don't have prelude-ido enabled in your prelude-modules.el.
