How can I better control the playback queue?
AFAIK you can only add songs to it and after that not move their positions in this list, you can not delete a special song in the queue so you can only see it.
Is that true or am I wrong informed and it is possible to do that?
Would be very nice.

And one other question: If I hear a song in the normal playlist (e. g. song 23), add then a song from a total different position in the playlist to the playback queue (e. g. song 3) and after that is be played the song after the first played song should be played (song 24).
How can I do this?

Thanks for help!

The playback queue was not meant to be manipulated like that. It's a short-term temporary playlist. If you are too indecisive for it, and if you want something as adjustable as a normal playlist, just use a normal playlist.

But it is not so easy to add songs from different playlist or from the search form to a normal playlist like it is to the queue (just middleclick on the song)

since components are already able to add items to the queue, remove items from the queue, and also see what items are in the queue, the ability to manipulate the items in the queue in any way is already there. its just up to the component to keep track of whats its doing with the queued items.

the only thing that would improve the core's queue functionality would be to make playback to return to where it left off once the queue is empty. sometimes it will continue in the playlist of the last queued item which is undesirable.

there are already some components that allows to remove tracks from the queue:

• foo_uie_queuemanager
• foo_queuemanager (obsolete doesn't support columnUI)

they only allow to remove tracks from the queue, but not to reorder them, but its quiet useful anyway

But you could asign a shortcut to send the selected item(s) to a specific playlist, and after that, you can fully edit the "queue" playlist, like shuffling and that kind of stuff.

Of course the problem with this "playlist is the queue" is that you have to keep feeding items to the queue...

Right now I have my default playlist, and when I think "hey I want to hear some Foo Fighters" I add some songs of them to the queue and when they are done playing, playback of the old playlist resumes...

Actually items can only be added at the end of the queue (they can be removed from any position). The only way for a component to reorder the items would be to remove and re-add all the items after the position where the change has occurred, which is not a very good idea since every single operation that changes the queue may trigger other events.

But I agree with others that the the ability to reorder the queue is not really necessary.

Another component for removing items from the queue is foo_removefromqueue.
