I feel somewhat like justintime on the issue. I have absolutely no need for a slider. Just out of curiousity, what does everyone else need it for?
If i'm listening to music, i'm not going to take the time to 'slide' through the song. I don't need to know where I am in the song (there is a well-working reverse count in CF)
I mean, honestly, I don't understand WHY you would need it?
