Hello. I like that I can share PDFs online and get comments right in the doc. It took me a minute to realize that when I selected copy and left a comment that it didn't attach that comment to the copy. I had to highlight the copy first, then leave my comment. Even after I discovered it, I kept forgetting to click the highlight icon before submitting my comment. It wasn't natural for my workflow. You should consider changing that feature so when the user selects an element, then leaves a comment, it is automatically highlighted (or otherwise linked to that selection)
