Clearer first start: an "Allow Sidetrack to play videos in this tab" button, a "ready" notice, getting-started tips (that you can turn off) and, the first time, a choice to tuck the player tab away or keep it visible. Playlist and Blind test are now separate tabs: the blind test plays the playlists you tick (one or several), and going to the Playlist tab no longer stops a game. Blind test settings in three groups with one-click presets (Express, Classic, Chapters), a number of rounds, tracks not played yet first, a replay button, keyboard shortcuts (Space, R) and a summary of the rounds at the end. A progress bar everywhere (click to jump), the video preview is now an option (off by default), and the link of the YouTube tab you're on fills the field by itself.

Your own name is highlighted in the chat. Until you pick a nickname, it is offered above the room form before your first room. French texts reworded.
