Once thing you start running into when you have many buffers is colliding names. For instance, if I open up two files
~/bar/test I would have two buffers named
test<2>. This depends on the version of Emacs, but is not very attractive.
(require 'uniquify) (setq uniquify-buffer-name-style 'post-forward uniquify-separator "::")
Now those two buffers would be named
test::bar, which I find more palatable.
