Oh, thank you, I just looked at how it works and tried it 
No, this plugin broken, don’t wanna animate
did you correctly used it like the script/keyframe. because it actually work very well.
what does this mean and how to fix it?
just tell me where is your problem in it and i may help you
I selected Frame clicked create, and then I can’t do anything else, nothing is added
when you click create there is a textbox written enter property something like that right ? so you have to write the property you want to animate like if you want to animate the scale simply write scale in it or if you want the position simply write position.
