First of all, LOVE your application, use it on a daily basis.

I would like to have an option of searching within my bookmarks or notes only.

Thanks so much for keeping up this great job.

So do you mean searching within the text of all verses that are bookmarked or verses that have notes, or do you mean searching within the notes you've taken?  Or both?

Basiclly to search within the text of all verses that I've bookmarked, but also searching within the notes I've taken could be useful.
