At this moment, the awesome right sidebar does not list all the streamers (Sonic, LoveTV, and other great casters), and I don't know whether they will be added.
Besides the sidebar, there are two other lists that I am aware of. The first is Afreeca's official BW list. It has the most up to date information, but it is hard to tell who the streamers are, for example, Bisu's ID is rlaxordyd. The second is TL's Wiki liist. This list is based on the snipealot database. The problem with this list is that you cannot tell if the stream is online.
Thus I created a table to list the streams (thanks to alexoundos for the snipealot list), the nicknames that we know the streamers by, along with some other information.
I hope others find it useful.
