Allow cycling of add to queue position

[looowizz]

Hi! Absolutely love the feature to add songs to specific places in the queue.

I think it'd be great if the position cycled to the end of the queue when clicking the "-" button at the beginning of the queue and back to the start when clicking the "+" at the end.

i.e. clicking the circled button would change the position to add the song to the end of the queue

This would be really useful when wanting to add a song to the end of the queue as we don't have to spam the "+" until we reach the end of the queue :)

Long-pressing the button should jump to the start/end of the queue
