If I have opened up a Passage Guide on, for example, I Peter 3, and after L4 is finished giving me my results, I would like to be able to search for a particular resources that I have on my mind. For example, in the I Peter 3 example, I have J. Vernon McGee's resources on my mind. I would like to be able to narrow down the passage guide, and the exegetical for that matter, resources list.
I hope this makes sense.
