Limitations
This is still in development and is done as a side project. It is meant to be lightweight so coverage is likely less than some proprietary plugins. The goal is that it will run better and provide more control than the heavyweight plugins. Also note that this cannot protect you from mobile spoilers so keep your guard up.
