The Antetype viewer could be enhanced by allowing the properties of cells to be viewed. This would be great for developers who don't need Antetype to design anything, but do need it for CSS properties. One idea would be to just add this functionality to Viewer. But if that's giving away too much, maybe you could add the functionality as an in-app purchase at a reasonable fee.
Copy CSS and right click to export individual elements would also be very useful to devs.
That is an interesting idea Ben - to expand the viewer with some tools that would be of use to developers and add them as an in-app purchase.
What other tools would be useful to developers?
What about reviewer tools or tools for other types of users that use the viewer?
