[Edit: part of the functionality I suggested is already available, updated post.]
I just recently started using Rockbox and really love it (on a Sansa Clip+). However, there is one feature I really miss: clearing the currently queued songs in the dynamic playlist without stopping playback. I know I can clear the playlist by using stop, or by rebooting, but I would like to be able to do it 'on the fly'.
Sometimes I'm listening to a song, and decide it will be the last, but there are still songs queued. I don't want to abruptly stop the current song, I also don't want to have to stay ready to stop playback when it finishes so the next song doesn't start. Currently I believe the only way to clear the rest of the queue is to remove each song by hand?
Another option I would really like is the "Play next" option but then shuffled (i.e. "Play next shuffled"), such that the dynamic playlist is cleared after the current song, but still the selected music is appended to the playlist in a random order. (Queue and insert don't clear the rest of the playlist.)
I hope others see the benefit of such functionality
