I've wanted a script to move tweetdeck to the appropriate screen in Spaces depending on whether I have a secondary monitor attached or not. The initial version doesn't do anything more than set the property for tweetdeck to be on space 4 or all spaces depending on the display configuration.

Once I figure out how to get the sizes of the displays, then I'll move it to the correct coordinates as well. Then the next step is to figure out how to detect display size changes and execute it automatically. But, for now, I added a bash alias that I can use to run the script.

alias organize="osascript /Library/Scripts/Basics/Organize\ Monitors.scpt"

The most up-to-date source to the script is out on github.
