Since Highlighting is now part of Notes, and we can have as many unique Notes as we care to (i.e., for a resource), it seems to me that it would be advantageous--esp. WRT Bible study--to be able to open, say, the ESV in two tabs (or windows) and have different visual filter selections active in each.
For example, one Notes file might be used for highlighting meant as teaching aides, while another Notes file might be used for Original Languages-related Highlights--and having both active in one ESV window would be more confusing than helpful. Perhaps this would also be helpful when projecting a floating window of the ESV, but having a highlighted version visible on your computer monitor as a speaking aid.
I'd create a UserVoice suggestion, but I'm out of votes...[^o)]
