This is specifically for website reviews, but feel free to chime in about mobile as well. How do you usually review an implementation of a design and approve or comment on it? Are there tools for this?
Ideally I would like a screenshot or a live build of a design, and annotate on certain sections and send it back to the dev. If everything looks good, I would want to mark it as complete.
TL;DR Layervault for engineer/design reviews
