Give streamers possibility to break for commercials
Like on TV, every 45-60 minutes or so, streamers should have the opportunity to break into video commercials. The stream shouldn't never be interrupted suddenly though. Streamers shall receive a notification when they are able to send another commercial (if they want to), and it is up to them to evaluate the best time to do so, not to ruin the streaming experience for viewers, eg. in-between two matches of a game. Once the commercial is over, the stream shall resume automatically.
This would allow you more money for extra commercials and extra monetization for the streamer breaking to commercials.
Streamers have the option to run ads. Doing so prevents preroll ads from appearing. You also get a timer showing how long the prerolls are suspended for and if you try to run an ad too soon, it will not let you. There is an internal timer. Some streamers like Devin Nash promote rolling your own ads and he tasks his mods with keeping track of it.
