Tracks are now automatically assigned randomized colors, which you can change by clicking on the color swatch.
Those colors are displayed in the vertical navigator making it easy for you to locate your content.
While you can use the mouse wheel to resize tracks, you can now also select a track.
Go to Multitrack, Track, and choose Minimize Selected Track to fix the height of the track so that it's ignored when resizing with the mouse wheel.
Audition can export to Dolby Digital audio files, and the track panner makes it easy to set up surround sound mixes.
Simply select the track and drag the control puck around in the surround sound space.
