Please add a way to stop audio files from playing instantly, as soon as you open them.
On the Dropbox app, using an iPhone, the minute you open the file it starts playing.
If you have previously played that audio file and paused it half way through, you can't stop it from playing in time to take it back to the start.
We use Dropbox for our choir and keep our backing tracks and sheet music together.
During a performance we need to make sure all the files have been returned to the start and we can't have them ready to go to press play.
