It would be nice to be able to scrub while still hearing the music/audio. This last thing is useful to find a piece of audio you're looking for and the first thing especially if you have a long piece of audio such as a podcast. Also to be able to adjust the speed of scrubbing, so for example sliding your finger/mouse upwards when scrubbing, halfway your screen being 1/2x and on the top of your screen 1/4x (like in YouTube).
