shuffle button plus bug

It really annoys me that when you click on playlists on the pc app it shows the playlists and has a purple play button, but it always play thebplaylist from the begining. There should be another button next to it to play songs from that playlist straight from a shuffle, like a shuffle button

Next is a bug when i add a song to play next on my queue is dissapears or retarts if i click play on a song before the play next queue is played. This is pretty annoying as i constantly add songs to play next but also want to listen to a different song then the current one playing and losing my queue of play next
