Basically, I really like vi[m]'s key-bindings, but not the rest of the editor. I really dislike emacs key-bindings, but like the rest of the editor.
viper-mode
seems like the best of both worlds, but it's not perfect..
What vim features did you miss in emacs (and more importantly, how did you get them back)? What config-tweaks did you do to make viper-mode nicer to use?
As a start: I really missed vim's visual-selection mode.. vimpulse adds this to emacs!
