The volume controls are okay.

The seek control is what I really want. In fact I would like to be able to jump to a specific time tag like you can do in xmms. Also, what would be cool is to be able to jump forward and back by small fixed times (again like you can do in xmms) - not sure how you can do that with limited keys.

A slider would not be as useful for me because I don't think I would have precise control.

The existing seek control seems okay, but I do have one long audio file (58 min) and it is slow seeking through it. Also I get a different max time for the seek each time I enter the seek menu. I am sure it wasn't built for an audio file that long.
