Youtube Playlists on the Android App

I noticed something on the Youtube Android app that I hadn't noticed before.  It seems like a recent update to the app allows you to watch a user's playlist.  This is something that I have wanted for a while now.  A lot of Youtube organizations will upload multiple shows to a single channel.  The channel owners will often make playlists for each show, making it easier to watch older episodes of that show, or watch a series of episodes in succession.  The problem was, the Youtube app didn't support that.  I had to select a channel, then look for all the episodes of that show.  There is a dropdown on the top left of the screen that originally had "Uploads" and "Activity" as possible values.  Now, "Playlists" is in that dropdown.  I can finally watch older Crash Course History or Tabletop episodes with ease!
