I believe one of the biggest flaws of today’s tools is their failure to allow designers to easily work with real data. Because of this, designers often fill their mocks with idealized information that is anything but representative. Beautifully composed photos. Perfectly sized bits of text. Just the right amount of content to fit. We spend an inordinate amount of time making our pixel-perfect fabrications. We then make sub-optimal decisions based on this, considering only our single, perfect state. We are surprised when our designs are implemented because we forgot to solve a variety of edge cases and problems. When we don’t work with real data, we deceive ourselves. - Medium
Aside from the valid points made in this article, I would love a tool to easily parse and visualize JSON files on OS X.
