Adding a comment when creating a bookmark works great - and is a feature I would have never thought of. But, edits made to a comment, from the bookmarks view, are not saved. The same goes for adding a comment to an existing bookmark. Unless I'm doing something wrong.
Thanks for letting me know about this. I have had this happen sometimes, but can never "force" it to happen so that I can locate the issue. I have found restarting the app seems to fix the issue for whatever reason. I will look into it further...
