The Adobe Comp App for Creative Cloud is a great tool for mocking up all sorts of layouts. The connectivity to the Creative Cloud marketplace and also your own creative Cloud library makes it an essential tool.

Layer on that the gestures to create quick headlines, image blocks and text blocks makes it fun. 

Then it gets a little Big Brother!  Just click the button in the app that says “send to Illustrator” and BAM it opens Illustrator on your computer and opens the file for further editing and fine tuning.

I am planning on putting a lot of thought into how to implement this into my own design process and how to use it with clients!
