//
// Thanks to AltoRetrato and his work with the great "IMDb 'My Movies' enhancer" Userscript.
// https://openuserjs.org/scripts/AltoRetrato/IMDb_My_Movies_enhancer
//
// This userscript highlights movie titles, series titles, and people from your lists. This way, you can immediately see which
// movies or series you've already seen or have on your watchlist while browsing IMDb. If you have lists of your
// favorite actors/actresses, you can see them highlighted in the calendar when they appear in a new film.
//
// This all works so far, with a small limitation. Custom lists and watchlist working fine. Unfortunately,
// the ratings list and check-in list don't work via automatic import. You have to take a detour for that.
// You can either manually import the ratings CSV file (which you downloaded previously) or create a custom list
// and add all rated films to it, which you then import via the script.
//
// A "Configure List" button will appear on the list page. All recognized lists will then be in the configuration,
// where you can assign each list a unique color. If you simply check the box next to the list WITHOUT uploading
// a CSV file, the lists will be imported automatically (as mentioned, this unfortunately doesn't work for
// ratings or check-ins). If you check the box AND upload a CSV file, the import will be done manually.
//
// As soon as you click Start Import, all lists to be imported will be displayed, along with a progress circle.
// When the import of a list is complete, the number of imported entries will be displayed next to it.
// After the import is finished, reload the page, and all imported entries should be highlighted.
// All custom colors will be saved. You don't have to import all lists at once — nothing will be lost if you import
// another list later. Clear Data deletes all data!
