Okay, i agree on this.

But still, can we improve the bindings a bit? Since pressing `alt + cmd
+ left arrow' would make all my fingers leave away from the basic key
positions(i meant `asdf' and `jkl;' on us keyboard) Say, how about
changing it to `cmd + left arrow', which is not taken yet, right? I know
adium has this binding for switching tabs.

Worstly, can it be customizable? in camino.
