Mouse-Based Focus in Emacs
I do most of my work in Emacs: Latex, Matlab, various programming, etc. I have a big wide screen on my laptop (1920×1200) and I like to have one big Emacs window, with several buffers in split screens. I find it annoying that it has a click-to-focus policy for the split screens, in contrast to X (Obviously there are keystrokes, too). Luckily, someone has solved this problem.
