Script Summary: Highlights links, movie titles and display tooltips on IMDb for titles your have in a list (i.e., "Your Watchlist", "Your Ratings" and any other list you have created).
Update: now working with dynamic links and images, since version 1.26.
The IMDB "My Movies" enhancer is a script for the Internet Movie Database site. When installed, it will highlight all links for movies you have added to your lists (i.e., "Your Watchlist", "Your Ratings" and any other movie list you have created).
That way you can check the Top 250 movies list and see which ones you still didn't watch. It also works on any director, actor/actress, producer, etc. page, so you can spot their works that you might have missed.
At the moment, the movies are highlighted in 3 different colors by default: "DarkGoldenRod" for movies in the watchlist, "Green" for rated movies and "DarkCyan" for other lists. The colors are selected in that order (i.e., a movie in the watchlist and in any other lists will have the watchlist color; a movie in the ratings list and in any other lists will have the ratings color). You can select different colors for any list by editing the source code. I might create a GUI for this in a future release, though...
The script also enables you to open your lists by default in compact mode with reversed sort order, a bit like how the old lists used to work before the recent new layout created by IMDb.
To enable or disable any of features above, please visit Your Lists page on IMDb (while logged in).
