A quick way to list your rewatched anime on MyAnimeList. And also reread mangas.

//Run this only on modern anime lists
var totalnum = $("td.data.number").length //Count total completed entries number
// The 6 lines Below Will Click all links labeled 'More' to get the rewatch counts later on the page

for (var i = moreLinks.length; i--;) {
  if (moreLinks[i].innerHTML == 'More') {
    moreLinks[i].click();
  }
}

function loopscrape(){ //Remove all entries that were not rewatched
  if (totalnum === document.querySelectorAll('tbody.list-item tr.more-info strong').length) //Check If The total completed entries number is equal to the total number of more links opened, And If Yes These Codes Will Run
{

    } //Remove the entry from the list
  } //Finish the for condition
