In earlier versions of Vox the track slider reflected how much of the track was already played by simply an orange line on black. IMHO it was fully sufficient and nice to the eyes.
In the newer versions the orange line is always present (???) and the part that has already played is marked by just a thicker orange line. I am not even sure I am able to explain this, but it is really ugly and inconvenient. It also puts additional strain onto the eyes instead of being simple.
