i think it's not possible with 0.6. when i have two tracks in my playlist i can only seek to position 0:00 when track 2 is playing. not into the end of track 1. (when seeking backwards of course).

my sony cdp-xa-20es also has this "feature" and i think it's very useful.

I remember this being discussed before, and people telling me that it was very, very difficult to impliment. Thgis does not mean that it's immpossible - I'm sure zZzZzZz is clever enough.
