I spent way too much time on a tiny menulet that just switches Mac audio from stereo to mono. http://charlesism.com/monomenulet.html http://charlesism.com/monomenulet.html It's simple, but I think I think I made it nice to use. A couple minor details I added: you can change its keyboard shortcut directly from the menubar, and it flashes the keyboard backlight to get your attention.
