The newest version of Explain Everything is now in the App Store. It includes WebDAV integration which is great for institutions that have their own proprietary file server.  All of Apple iWork apps have WebDAV integration and now we have joined the fray. 

We have also made continued improvements to the shape tool including the option for turning shadows off and improving the outlined shapes for annotation.

One of the most requested features has been to make inserted photos align to a grid when they get moved or scaled.  We terminated the double tap to rotate feature and now have made it so that double tapping an image will align it to the nearest 90 degree orientation when it is within a few degrees of that position.
