ScriptLight does what Spotlight does not. ScriptLight allows you to search and manage source code files on your computer.
With the number of files many of us have on our computer it becomes almost impossible to find code we have already created. Spotlight doesn't even allow us to search our Applescript code files and Spotlight doesn't index all of the folders that hold our other types of source code. Well now there's ScriptLight which allows you to have all of your code files in one place. You'll rediscover files you forgot you ever had!
