I just tried out Dark Mode--I really like that as an option; could see myself using that in set in dark situations. HOWEVER, I'm someone who likes to use the freehand highlighters (as well as the text highlighter), and the freehand highlighters don't work in dark mode; what should look like a flourescent yellow highlight actually turns into a dark 'cloud' that's easy to miss completely (and even slightly obscures the writing or drawing it was meant to highlight). Once again, I appreciate the Dark Mode; will love using it once it's tweaked!
