Usability enhancements

Hi, First off, great product. I would really like to blog about it and promote it to more designers. Not just graphic designers, but all of us in the user interface design community. This can be a much better tool than BaseCamp for managing design files. I was wondering if you are open to some usability enhancements? Number 1- Can you mark the items in the collection that have comments, otherwise I have to click on every picture, view details, and check to see if it has comments or not Number 2- provide a daily summary or way to subscribe to a RSS feed of activity per collection. Then it would be easy to see who commented, who responded, who approved changes... Number 3- Down the road, have you considered allowing for direct commenting on a screen like MockLinkr and ConceptShare do. It is a nice way for people to point to specific parts of the screen and leave comments or ask questions. Thanks, Theresa
