This plugin does the job but not well enough to my opinion.

I came across a few bugs and quirks like :
– The number of generated items does not match category count product (you’ll need to disable category count to keep navigation consistent)
– It generates invisible items for products that are not published yet (draft, import list, etc …) which results in a few empty pages.

It would be a great feature to be able to choose the attribute we want the plugin to use for splitting variations. Instead, it splits according to all the attributes. (ex: it splits by color but also by size)
