Today I added some commands that you can use in the heylisten chat.
/help - prints some notes on how to use commands right in the chat
/me - works the same as the IRC /me command
/adduploads <platform> <channel> <number of videos 1-20> - will add the specified number of newest songs from the specified channel from the specified platform.
So for example
/add youtube mrsuicidesheep 10 will add ten sweet songs from MrSuicideSheep to the playlist.
/addplaylist <playlistID> <number of videos 1-20> - will add the specified number of songs from a given youtube playlist.
/addplaylist PLDfKAXSi6kUba6EDLtCojcKg45Uwp39Bh 10 will add ten songs from this playlist.
I also added a shortened versions of the last two commands so if you don't feel like typing too much use
Right now the add command only supports YouTube, but I'll be adding support for SoundCloud and Vimeo very soon. As time goes on I will be adding more commands so stay tuned for that. I'm also looking into adding emoji to the chat since someone already requested that.
