I generally enjoy seeing what other people have highlighted with the light gray underlining, but this week I ran into a passage in the New American Commentary where for 273 pages, the text from John 1:1 to the end of chapter 6 is completely underlined, which make the underlining annoying rather than helpful. I think Logos needs to set a limit on how much text the community highlight will show. ie. if a large enough section is highlighted that it disregards the highlight, and if a lot of highlights occur in the same section, then the ones that are least high-lighted don't show up (or the underline is much more faint)
Also, I can't seem to find a setting in program settings to turn off this feature. (I tried turning off "show community tags" but that didn't help). If there isn't a way to turn off this feature, I think there should be.
