There is already an option to follow and not receive live notifications, but what about having a system where you can get live notifications without following? Maybe you want try and follow when they are live or maybe give them a few moments before making the decision to show support by following. I think the option to receive live notifications without following would be a tool people would use. There are multiple times where I want to follow someone when they are live, but the problem is, I have no idea when they go live. Some people don't even have a schedule. Some people don't use Twitter to tweet when they go live. But maybe adding like a bookmark feature or something that would allow you to get live notifications without directly following the user. This would not be visble to anyone except the user who bookmarked it. Then when the time is right, and they want to show support, they can follow the user to represent their support. It would allow people to know exactly when the broadcaster goes live without needing to follow them at that moment in time.
