Does anyone know of a setting/automator-task/third-party-app that will allow me to automatically change the dock position based on some event? I use an external monitor in a configuration above my MBP, so the laptop keyboard and trackpad are my input devices. This makes the 'bottom' position of the dock quite annoying, but I prefer it to be there when not using the dock. Ideally I'd like it to automatically change dock position to 'left' when the monitor is plugged in, and then back to 'bottom' when the monitor is unplugged. Any ideas?
