I really appreciate the Personal Book Tool. There are two features I would like to suggest!
1. My church has to work on some Bible studies for our congregation. I would love to be able to compile them for use in Logos (and eventually mobile devices) for use. I even hope there is a way for church members to use them. I would really like the ability to add boxes for answers to be typed in (like a workbook). Example found in "Grasping God's Word" by Duvall & Hays
2. I love the new sermon and illustration options for the Personal Book Tool. I would love be able to embed video or audio within the Personal Book. My church records our worship services and makes them available for download. It would be so awesome to be able to have the sermon notes or manuscript and recording of the sermon. The same could also be true of video/audio sermon illustrations.
Thanks!
