Thank you for the mention.We built zipBoard with the idea of making it easy to share all that design feedback and converting them to issues and tickets.
We capture all the information and tag comments to the DOM element -screenshot, url, browser and session) with that issue.
Another thing that we do well is ability to even capture small videos, if there is more interaction.
Plus the ability to manage issues for different environments in the same project, staging, dev, live.
