Supporter and/or Subscriber only Stream Mode
Add a way that streamers can have a special stream only for their supporters and or subscribers. This is not to lock out the rest of the viewers. But to give some special attention and exclusivity to those who support a stream channel. It would just be a switch to toggle only subscribed or whitelisted viewers would be aloud to enter the stream.
This would also encourage those that have not supported the channel to do so to be included in on the exclusive and special event streams that are only available to supporters and subscribers to the channel.
Maybe add an option for a specific link to invite people as well?
