Editing playlist options + playlist images.
First of all, love the playlist pages! Really happy with this update :D.
Probably a next step that's already on your agenda, but playlist editing (outside of current cue) would be a great thing too. Both editing playlist in the playlist page, and having an option to add to playlist from others' (I feel like I mentioned it before but I can't find the tread so quickly, so appologies if it's double).
On another note, I was wondering, is there a reason there are no pictures? If anything I'd expected it to be using first or a random album art from the playlist like it does on mobile and other pages on the web player seem to work in a similar fashion (if you plan on making an editable image selector, it would still be nice temporarily if not too much trouble. But I can understand leaving it out in that case if it would be a lot of work). It looks a bit odd now.
