The previous Edge supported 'Add Note' i.e. as a symbol in the 'symbol-list'. This is very useful and should be also be available in the new Edge. I used it heavily to make notes to a website, than I saved it and shared the website including the notes with friends.
@Juergen_Soltau Same here. Hope to see this in the new Edge but one of the usability things that i disliked from the old edge was how it handled the comment bubbles in the Add Notes feature. I would add my notes and try to share it to my team, however, the comment bubbles collapse and get sent as an image. It would have made such a difference to my productivity if i was able to do this because i review my team's web designs and copy often.
