How could you ever consider it appropriate to hold hostage a good rating in exchange for a feature that this extension never promised? The extension either serves its purpose as listed in the description, or it doesn't.

This is an extension built and offered for free. I don't have to do this. I chose to because it is a nice thing to do for others like you. Yet somehow, a few people feel entitled to more. You are essentially pressuring me to provide you more of my time and energy. I develop features as I see a personal need for them and then generously offer them to others to use if they find them useful.

Comments like these make life unnecessarily difficult for open-source and free software developers.
