Bible study journal

There are a lot of study Bibles out there with some fill in the blanks for writing stuff. Some of them have commentaries. These might not be as useful for people who really know Scripture and want to dig into it more. If you had a study aid to go along with a book (for example, Ezra), what pages would be useful? For example, a page for journaling? An outline? A section for verses you want to memorize? What would you actually use? I am not thinking about making a commentary, but an open tool to encourage people to do their own digging and reading a long.
