Whilst Comp is a version 1.0 product and has barely been out for a week, it is already showing good potential, and generally seems to offer a smooth and stable user experience. Using it I have been able to quickly mockup an InDesign document, bring in images which I had saved into a library within Photoshop CC, and vector artwork (a logo) that had been saved into Illustrator. I was able to quickly position them on the page, together with additional text and content, and then push the completed document out to InDesign. The document opened up pretty much straight away in InDesign where I was then able to carry on working on it.
