I am officially a Born again Media Manager Convert. For a while I had just disabled it, but now after collecting tens of thousands of video clips and audio samples, Media Manager has become an integral and invaluable tool in my work flow. It really searches fast and the list view with thumbnails performs good even when scrolling through lists of 10,000+ media items.

It is extremely useful when working collaboratively because you can quickly find content so as to not disturb the creative flow.
