zinf should remember the current track position. Ok it remembers the current playlist position but not the current track position.
On the next start of zinf it should resume their.
You know car radios that resume their play on the last position of a cd/track if the car starts? :)
1. It should remember the position if the application exists.
2. zinf should know it is closed externaly by the OS (e.g. a kill because of a shutdown) and remember the position.
