Vim

I just want tabs inside windows, nigger. Not the other way around.
^W-[hjkl] is more work than g[tT] so it should represent a less frequently used operation.

If I use screen I get to run yet another fucking daemon just so I can load up each Session.vim individually, set vim's default yank buffer to * and have it still not work properly, and to top it off use Emacs shortcuts to switch windows. That sounds fucking great.
