ido-ubiquitous

Gimme some ido... everywhere!

Does what you were really hoping for when you did (setq ido-everywhere t). Replaces stock emacs completion with ido completion wherever it is possible to do so without breaking things.

Get it from http://marmalade-repo.org/packages/ido-ubiquitous

Note that ido-ubiquitous is not enabled for org mode or magit mode, because those modes have their own support for ido.
