[Prestashop 1.6.1.5] Comments and gardes

[PsychoZzzorD]

Hi everybody,

I would like to put in place two options for my customers.
They should be able to only comment and only give a grade.

But, with the productcomments module, I successfully customize it to only show either the comment or the grade, but the two are linked anyway, you can't just send one without the other.

I've thought that split the productcomments module in two is the solution, but I don't really know how to proceed.
I know that I must copy all files and rename them, but is there a more viable option ?

Can someone helps me ?

Thanks in advance

Paul
