1. I would like that you have the option to remove previous songs when you shuffle the now playing list. This would be nice because you could add a bunch of songs while still listening, and then when you hit shuffle it would remove all previously played/skipped before the currently playing song and then shuffle the remaining tracks as it currently does.
2. If you are in the shuffle collection mode, an option to be able to add tracks to the list that would play immediatly after the current song, then resume randomly shuffling through your library would be great. This would be useful when you just want random music, but occasionally want to hear a specific song.
I use subsonic at work for about 10 hours a day, can you tell?
