I have five suggestions that would greatly increase the usability and intuitive nature of logos. As it stands currently, it is really hard to figure out how to be effective with precise search.
1. Create a single, easy-to-browse reference list of all search syntax and operators, with short descriptions and links to details.
2. Have the syntax and operators come up as suggestions in the search
3. Make all Bible Browser data sets (like prepositional outlines) searchable and available for visual filtering.
4. Allow users to customize Speaker and Addressee markers (colors, styles, logic) and give more detail when hovering over the icons to tell you who is speaking and listening.
5. Add an “All Speakers” option in visual filters or markers to highlight every instance of speech without having to select each speaker individually.
