Request from customer in the forum:

So how do you change the size of what we see on the ProductivityBlocks screen? I need to be able to zoom in and out to collaborate and share code with a small team of people on a roll around 55" 1080p screen. The default view is very small and I cannot figure out how to make the images bigger.
