Winamp has a feature I love: the right arrow advances about 4 seconds in a track, the left arrow goes back the same. dBpowerAMP has the ability to set keys to go forward and backward, but it adjusts 5% of the file at a time -- which is often a heck of a lot more than 4 seconds. It would be nice if the amount of movement could be set in seconds rather than in percentage of the file.
