While the new (in 2013) preview has really helped people plan their displays and improved sequencing with the ability to see instant feedback, you have not been able to really get in and fine tune the props displayed on the screen.
After the alignment tools added last month, the second most requested feature for the preview was the ability to zoom in and out.
You can now zoom in and out with the mouse wheel, the Ctrl+ and Ctrl- keyboard buttons or the slider located in the status bar.
As usual, here’s a video showing off this new feature. In addition, the video also shows how to add a snowman with 3 body parts, a left eye, a right eye, a nose and a 3 section mouth.
