Click on the buffer bar to forward a little the track
What is the problem you are facing?
I often feel like advancing the music a little bit but you can't do it from the buffer bar, I often click on it thinking it's going to work but it doesn't work.
I would find it useful to be able to do it directly from the buffer bar, and more ergonomic than having to open the window every time I want to move the track forward a bit.
