Since Adobe Review is discontinued, I used with a couple of clients the new creative cloud sharing and I found some missing features or improvements needed:
1. When a client is reviewing a file (i.e. a picture) he must input the email address to post a comment, this is annoying since I sent the review email to his address, so it's already verified.
2. An important improvement would be a way to make a note (or link a comment) on a specific part of the picture/text so the comment can be highlighted in the context.
3. I'd like also to receive a notification of new comments or see on the dashboard if new comments are present on a file, so I can review all the latest comments.
4. There could be a button for "approval", if I put several versions of a work, client can approve the one he likes.
Maybe some features are still present, please tell me if I'm wrong.
Thank you for the suggestions. Improvements with sharing and collaboration are coming. You can read more here on this Adobe blog post http://blogs.adobe.com/creativecloud/coming-soon-to-creative-cloud/.
Feel free to add more suggestions to the blog post or follow up here with more. We are listening.
