Being able to quickly resize to suit multiple platforms, purposes and media

The template-based concept makes it pretty simple from the get-go, because there aren't any major design choices to be made. The entire process is basically drag-and-drop. But the real beauty of the app is the ability to easily click between templates and/or between sizes and shapes of "matched" templates, to create multiple variations of the same thing with just a few clicks. (This is amazing, for instance, if you need banner ads in six different sizes.) Recent updates have added some helpful features, like the ability to snap objects to center.

I love the pre-made templates. You can create on the fly.
