Suggestions on how to improve the Catholic Topical Index

Currently, each entry has one or more of the following four sections: Sacred Scripture, Church Teaching, Canon Law, Ecclesiastical Writers.  I would like to suggest the addition of two more sections: 1) Dictionaries/Encyclopedias 2) Bible Commentaries

The newer Study Bibles and Bible Commentaries have "word studies" and special notes that it would be fantastic to have included/linked. I am thinking specifically of the Ignatius Catholic Study Bible and the Catholic Commentary on Sacred Scripture.

For the Dictionaries/Encyclopedias, I am thinking about(hoping for) at the minimum: The Catholic Bible Dictionary (Scott Hahn) and A Concise Dictionary of Theology (O'Collins & Farrugia).

Also, having a few more entries in the index would be helpful.
This idea is nothing radical, it just builds upon the framework that is already in place. Anyone else have any ideas?
