We are very excited and glad to have implemented back-to-back BIG features for MockFlow, therefore adding more value to the product. Today's feature enhances the functionality of the 'Comment box' (found in the presentation mode). Now you and your mockup's reviewers can link and place arrows in the mockup to virtually point out what they are referring to in their comment. So now each comment can have its own annotation making it easy for the viewers to understand and communicate better.

Here is a live example. Open the 'Comments' and click on each comment to view the annotations. Tip: You can move around the Comment Box by dragging its header area.
