There are already notifications that turn on when you sub to someone though? If you're on mobile, just hit that top right blue button for the menu and your notifications are listed right there.
You can even change your notification settings to include or exclude certain actions from your notifications. For example, I turned off notifications for who gives me diamonds and for new subs.
The front page of the site also has a feed that fills up with posts based on your subs and what they post.
