I had a cool new idea for a new exporting option! In order to make it simpler to save your video so it is the exact same length as the music, there should be a feature that automatically does this for you. It looks at the length of the song or playlist and changes the length of the video accordingly.
I Photoshopped a design of what it might look like:
Sure, that's a good idea. Currently, the first time you open the Export window, it will automatically get the length from your audio. But if you change the length of the audio, it won't be updated for exporting. So your suggestion might work well .
