1. People have passwords on their phones = takes 4 clicks and a slide to log in.
2. The mp3 progress horizontal bar stinks anyway for tracks longer than 4 minutes. I listen to 50 minute tracks mainly (lectures)
3. The (stock) Double-Click Home Button when Iphone is "locked" allows you to:
a. adjust the volume
b. go to the next or previous track
However, It Does NOT allow you to change the track progress.
I request someone invent a digital touch round wheel to adjust the track progress which appears by double clicking the home button on the iphone (in addition to the current ipod control features that pop up.
Thoughts?"
