I posted this on a FB Logos group and thought I'd add it here to see what the forumites think.
What I consider to be a gaping hole in the usability of Logos is its poor graphical output tools. The screenshot below is from Biblearc, a web-based tool that is easy to use, intuitive, and can do multiple graphical wonders with scripture (phrase diagramming, arcing, bracketing, markup, and more). This phrase diagram of Hebrews 1:1-4 took me about ten minutes to make. Try that in Canvas, etc.
I suspect I'm not the first person to point at Biblearc so I doubt it's a secret to the developers and brass. But I sure wish they'd build something like this that is of similar ease of use, integrated into the (at least) desktop app.
