Just to add tweaks that I use with already mentioned Ido:

(require 'ido)
(require 'ido-hacks)
(require 'flx-ido)
(require 'ido-vertical-mode)

(ido-mode 1)
(flx-ido-mode 1)
(ido-hacks-mode 1)
(ido-everywhere 1)
(ido-vertical-mode 1)

(setq ido-enable-flex-matching t
      ido-use-filename-at-point 'guess
      ido-vertical-define-keys 'C-n-C-p-up-down-left-right))

I'm also using ace-window to switch between buffers together with ace-jump-mode to jump between visible windows. Comes with some getting used to but worth trying.

I have combined it with key-chord-mode and hit so for quick jump:

(key-chord-define-global "so" 'ace-window)
