I've been experimenting with this as well.

One way I've begun to start keeping lists of books to read, movies to see, wish list or ideas is:
Create a single action project and assign it to a default context of the same name:

Example:
Create Wish List Context
Create Wish List Project
Select Wish List Project
Open Inspector
Change to Single Action Project
Assign Default Context of wish List

Then I either place the project on hold (right click on project and set to on hold) or the context on hold (right click on context and set to on hold) to hide it from my daily workflow.

In my daily workflow I have the view bar set to active projects and active contexts.

Some of my lists I have different applications for:
I use Netflix Queue to track movies to see
I use SplashShopper for my grocery items. (Allows me to assign by aisle and sort)
