Google Search add-on

Google Desktop Search is a wondeful thing that you all should be using already(if you're on windows). One of it's weaknesses for hep multifaceted people like myself is that it's constrained to certain nice predictable file types, like microsoft office files, and .txt. But there are many other textual files, like .logs and xml and code you may write. This add-on allows you to specify which files GDS opens in it's scans of your hard drive.

Quite nifty and ratchets up the usefulness of the thing quite a bit. Now all it needs to do is spider network drives and start indexing meta data and labels better, allow constrained exhaustive searches, and increase the maximum size of file parsed.

Regular expressions are unneccesary but would sure excite a lot of people.
