Logos 5 supports touch gestures for scrolling and turning pages (on Windows).
Touch capability and stylus use is critical for use with a tablet. I have over 4000 books in Logos and would like an easier way to read them. A tablet is by far the best way to read books, as opposed to study the Bible (which is better done on a laptop or desktop). A simple swipe to highlight would be helpful too.
Syntax searches can be very complicated and time consuming to set up. Thus I would find it helpful to be able to enter a comment or description that would not be part of the search. It could appear in a non-searching text box or perhaps something like the information window on a resource. I often want to remind myself of the strategy I am attempting to set up, what stills needs to be added to the design, unexpected side-effects, questions about missing results, etc.
