The feature for viewers to be able use their points to upgrade to a VIP Level would be awesome.
VIP Bronze = 1.
ViP Silver = 2.
VIP GOLD = 3.
Viewer would type
!upgrade 1
and the streamer should be able to set the price for each level or only allow a certain level to be purchased.
For example I would like only VIP Bronze to be purchased and want it to costs 25,000 POINTS.
!Upgrade 1
bot then says: 25,000 points have been removed from your account and you have been promoted to VIP Bronze.
