MediaRiffle v0.5.0

✨ Features and improvements

• License: MediaRiffle is released under the BSD 3-Clause License, copyright TechIdiots LLC. LICENSE ships
  with every package (in the program folder, and as /usr/share/doc/mediariffle/copyright in the .deb).
• Sign in with Google: link your Google account under your name → Profile, then sign in with it instead of your
  password. Google only signs in accounts that linked it; people still join with invites. Off until an admin sets
  MediaRiffle:Google:ClientId and ClientSecret (see docs/configuration.md).
• A menu under your name in the top bar, with Profile and Sign out.
• Music libraries: a new library kind, browsed by artist, album and track. Songs are filed by their tags (album
  artist, album, disc and track number, year), or by Artist/Album/01 - Title folders and names; tracks with
  different artists and no album artist make a "Various Artists" compilation. Play all and Shuffle work on a library,
  an artist, an album or a category, and picking a track plays the album from there. MP3, AAC and WAV (and FLAC and
  Ogg where the browser plays them) are sent as they are; anything else is converted to AAC once and kept. Cover art
  from cover.jpg / folder.jpg, else the picture inside the files. See docs/configuration.md.
• Music keeps playing while you browse, in a player bar at the bottom of every page (cover, title, previous /
  play / next, seek, close), on the lock screen and media keys too. Now playing shows it bigger, with the queue to
  jump around in. The playing track is marked on its album page; after a reload the music is back, paused where it
  was. Starting a video closes it.
• Music on a Chromecast: the player bar's Cast button sends the queue to the TV, which plays through it itself
  (on with the phone asleep); the bar and Now playing follow and control it, and stopping casting brings the music
  back, paused where the TV was. The TV fetches songs and covers from 24-hour links that carry their own key, as it
  can't sign in. FLAC and Ogg go to it as they are.
• Favorites, lists and hiding for music: artists, albums and single songs go in Favorites and your lists (a
  song's ☆ on its album page, or its lists on Now playing); a list of songs is a playlist, played in the order they
  were added, and a song can be taken out with ×. Artists, albums and songs can be hidden like shows and episodes.
• Hide what you don't want to see: a Hide button on a show's or movie's page, on each episode, and while playing.
  Hidden things stay listed, greyed out (Unhide brings them back), but are left out of Play all, Shuffle (categories,
  lists, libraries and shows), Continue watching and the next episode. Only you see what you hid. Profile → Hidden
  lists everything you hid, to open or unhide in one place.
