Example AppleScript for re-arranging commonly used windows for a screen resolution. Eg. switching between laptop at 1440x900 and external monitor at 2560x1440 is a big pain, requiring a lot of moving around and resizing of windows. So instead you adapt this script, make a setup-1440x900.applescript and a setup-2560x1440.applescript, and run them…

setup-WxH.applescript
