The rationale for having a rating window at all seems to be that some users would like to decide which papers they want to read, or have read and “liked”. The first reason does not justify imposing this feature on everyone else. As to the second reason please let us remove this concept from serious research. I may offer some view of a paper in my literature review or discussion but I don’t need a rating for that.
If you wish to cater for those few individuals who want to rate so be it, but please make this field optional. It will be first change I will make to my new X6 installation!
