MediaBay Aspects
You can create configurations of the MediaBay window and save them as aspects. These can be recalled via the Media menu.
This is helpful if you only want to work with certain sound effect files that reside in a particular location, for example. Every item in the MediaBay that can be configured can be part of a MediaBay aspect. You can specify which sections are visible, which media types are browsed for, which locations are being scanned, and so on. You can also enter a search string and save it with the aspect.
