No offense, Yeats:

And what rough beast, its hour come round at last, Sprints towards Bethlehem to be born?

What, indeed? Donovan and I spent part of yesterday (and much of last night) improving our PyObjC app. Here's a sneak preview:

It's called MacGregor [*] and it provides for multi-document searching in saved sets. Clicking on any of the files (either in the source table or the results table) will show the details in the drawer, and double-clicking will open the file in whatever application owns that type. The search widget starts searching as soon as you start typing, and it takes regexp search terms.

I also got to do some more work with Thumbscrew, turning the thumbnailing behavior into a standalone app, with command-line options (many users wanted to be able to use Thumbscrew from the command-line as a script). It will be trivial to make Thumbscrew use it at the other end of an NSTask (so when you accidentally drag your whole iPhoto library onto Thumbscrew, you can stop the thumbnailing without force quitting Thumbscrew).
