I like to highlight as I read, but if I am reading in Reading View (F11), I need to exit into the regular view and open up the highlighting and highlight, and then if I want to return to reading view, hit F11 until there is something else worth highlighting. If I use notes it is the same thing, because I have to go to the notes window as part of that feature.
I realize that this might be a major coding issue, so perhaps it isn't possible, but I think even a limited highlighting option as part of the right click menu would be helpful, and well, less clunky. Or maybe there is an easy way to do this that I haven't figured out yet.
