// To-do (priority: [H]igh, [M]edium, [L]ow):
//   - [H] Refactor using EntryList library
//   - [H] Not all IMDb movies are recognized because matching is done by title
//   - [M] Make triangles more visible
//   - [M] Show name in tooltip? Maybe not needed if above is solved
//   - [M] Show in tooltip all lists where title is present?
//   - [M] Lots of clean-up
//   - [M] Delay autopreview for hidden movies?
//   - [L] No link between IMDb user and Netflix user, basically it works for a single IMDb user
//   - [L] hide selective titles?
//
// Changelog:
// ----------
// 2019.09.30  [1.4] First public version, correct @namespace and other headers
// 2019.08.28  [1.3] Make the list more visible (top right triangle instead of border, with tooltip)
//                   Fix unhide function (bug added in 1.2)
//                   Add priority in todo list
// 2019.07.06  [1.2] Fix working in pages without rows (i.e. search page)
//                   Fix opacity not applied in some cases/pages
// 2019.06.20  [1.1] Load My List from My List page
// 2019.06.01  [1.0] Hide "My List" titles outside "My List" (row and page) and "Continue watching"
//                   Fix user name detection
//                   Gets data both from locally hidden movies and from IMDb lists
// 2019.03.30  [0.1] First test version, private use only
