I ran a comparison of Amazon; https://github.com/AdguardTeam/FiltersRegistry/issues/962

Only 2 entries (excluding odd ones like `keywords`) in ClearURLs had not previously been in LUS. I'd call that a high success rate for LUS considering the latter's 80-ish entries for Amazon.

Essentially, it automatically removes unnecessary $/& values from the URLs, making them easier to copy from the URL bar and pasting elsewhere as links. Enjoy.
