Just wondering if it's possible to retrieve all items in a list instead of only 20 if I don't want to use pages?

It depends on the list but yeah most are limited to 20 by design. Partially to avoid hammering the APIs and partially because the TMDb api forces pagination for many lists.

The stars_in/crews_in lists to get a person's movies/shows support the "&limit=XX" param which will allow you to get more than 20 items. Also there is a user setting in the plugin settings to expand some Trakt sync lists (Collection, Watched History etc.) from 20 items to 84. Other than that, the rest are limited to 20.

Thanks for the clarification.
