I love the tool but it would be great if you could upload custom lists from IMDB to Trakt.
I have 2 lists in IMDB, 'MOVIES' and 'TV SHOWS'.
The IMDB wishlist doesn't seperate between Movies or TV shows which is why I have the two lists.
You could add two boxes for custom lists, then an option to add extra lists. You could just start with two lists for the MOVIES and TV SHOWS.
The list ID is gathered the same way you get the IMDB USER ID, from the URL at the top of the browser when you're viewing a list.
Example: http://www.imdb.com/list/ls038469432, here the list ID is ls038469432. You could input the list ID from each of your lists to import into Trakt.
Trakt has collections for MOVIES and SHOWS so each IMDB list could be imported into each list of the Trakt collection.
I don't use the Wishlist often so it would be really useful to have the two boxes for each list. Both boxes would have to be labeled either MOVIES or SHOWS for the Trakt collection list when you import.
