I recently saw this feature added to a note taking app I have called GoodNotes that I think would be awesome to have on Accordance.
It allows for a Display Mode in which only the Bible text (or other specific resource) is displayed via projector/screen. But I, the presenter gets to still see the entire interface - beit on laptop/tablet - and can add highlights, underlines, arrows, etc., while the students/congregation only sees the effects of my actions on the text shown on the screen.
Whatever gets shown could be switched from Bible text to commentary, map, timeline, etc., making the sermon/presentation/lesson way more interactive and a lot more intuitive for us the presenters.
Thank you for all the GREAT features already built into this AMAZING app!!!
