Why doesn't this have any meaningful reviews? This tool is INVALUABLE for searching AppleScript code, if nothing else, since .scpt files, the usual form of AppleScripts, aren't searchable as text, and therefore aren't reachable by SpotLight. I use AppleScript extensively for everything from short scripts to bind keystrokes to to significant programs. I'm always looking for something I did too long ago to remember much about or how to do something I know I've done but at the moment just can't remember how.
True, sometimes for non-AppleScript files if I have some idea where the file is a simple recursive grep (or something that does grep through a more convenient interface as many code editors have) is sufficient. And, because I develop code in a wide variety of languages and have a very large set of files I want ScriptLight to index, it does take a long time for ScriptLight to refresh its index. However, once the files have been indexed ScriptLight finds things very quickly through a convenient interface.
