Hi there i'ma try keep it short. (not :P)
Basically I feel a clear queue button at the bottom of the now playing list that clears all songs except the 3 that follow the currently playing song.
This allows me the user 3 songs worth of time or so to find the next songs for what I am listening to without disturbing the currently playing song.
In addition to this in the now playing section if it was made so that one could swipe left to move the song to the next to play song. And swiping to the right removed the track from the now playing (queue).
This allows me to put on a fully customizable currently playing song list just making the user experience that much easier.
--(not telling devs but suggested) for the swipe controls in the queue. By adding a faint arrow with an x next it so that it can bee seen that you swipe this way to removethe song and then on the move to under currently playing. Add a up arrow with a solid bar above and 3 thinner hollow lines below to signify that it is under the current song when you swipe that direction --
