// To-do (priority: [H]igh, [M]edium, [L]ow):
// - [H] List/color configuration is hard-coded -> make configurable
// Also, configuration should allow to skip downloading of unused lists
// - [H] Not all IMDb movies are recognized because matching is done by title
// (maybe use https://greasyfork.org/en/scripts/390115-imdb-utility-library-api)
// - [M] Move IMDb list functions to an IMDb utility library
// - [M] Download lists from GM_Config or similar, not from IMDb/Netflix list page
// - [M] Show name in tooltip? Maybe not needed if above is solved
// - [M] Make triangles more visible
// - [M] Show in tooltip all lists where title is present?
// - [M] Lots of clean-up
// - [M] Add comments
// - [M] Delay autopreview for hidden movies?
// - [L] No link between IMDb user and Netflix user, implement getSourceUserFromTargetUser
// - [L] hide selective titles?
//
// Changelog:
// ----------
// 2019.11.01 [1.7] Adopt Userscript Utils and move some functions there

// 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"
