Audio video separation and audio fade option
To be able to detach audio from video and delete just the video or just the audio, then be able to move audio from one video on to the next one via timeline, and give a audio fade option just like video when skipping from one to the next.
You can now separate audio from an audio-video clip by right-clicking the clip and selecting Separate Audio (or long press on mobile). Premiere Rush drops the audio file into the first available audio track and the original audio becomes muted.
Once you detach the audio, open the Transitions Inspector and click on Cross Dissolve to apply an audio transition to your audio clip.
