Authorization of Patreon
Allow Twitch authorization of viewers that are also Patron supporters. This will solve the confusion of supporters that do not use Twitch account names as Patreon account names. Also a special badge would be very convenient to represent even the viewer that is a Twitch sub & a Patron supporter.
Twitch gets no money when you subscribe through Patreon. Unless this was modified, there is no reason Twitch should do it. Patreon also lets you subscribe for as little as $2, and so only certain packages on Patreon would even be considerable to have special badges.
