We figured changes would be afoot after Susan Wojcicki (former chief ad guru at Google) became the head of YouTube, and it turns out, the first ones made since she got the job are all about playlists. Henceforth (or at least until the next round of UI tweaks arrive), the left rail on Youtube.com will have a dedicated "Playlists" pane that shows your personal playlists along with those from other channels that you've liked. Additionally, users will find a new "Playlists" tab on channel landing pages and get a new dedicated playlist editing page. The new features are rolling out worldwide over the next few days, and with them comes a new responsive, card-style design that fits "neatly on any screen size," per the company, and should feel familiar to folks who use YouTube's mobile apps. One YouTube for all, yo.
