Xavi Beumala and I were talking a few weeks ago. He was showing me a new Flash extension he was creating to offer some flexibility when searching for assets in the library in a way similar to Eclipse. Relying heavily on the "search as you type" concept, he created a very useful tool for finding assets in your Flash movies.

When I saw it, it was very cool. But Xavi has been polishing it, and has released it as an open source project at osflash under the name Alf (Advanced Library for Flash)

Alf has a number of great keyboard shortcuts to optimize your workflow. Check out Xavi's blog for details on how to use Alf.
