I think the new web interface is a vast improvement over the old, but there's still one change that hasn't happened, and it's annoying from a usability standpoint: the web player playlist only has the option to shuffle music if you scroll aaaaallllllllllllllllllllll the way down to the bottom of the current play queue. which is a total pain if you load up a playlist, but want to shuffle it. this should be another shortcut button like the repeat option. I feel like it also shouldn't be a function of the play queue itself (literally shuffling the order of the songs within the queue), but rather how the player chooses the next song to play (so you can toggle shuffle mode on or off); but that's a whole other logistical issue so i won't expect that kind of thing any time soon.
just a recommendation

EDIT: Just noticed that this post says exactly the same thing:
