i teach an interactive design course and with CC2015 lack of a previewer for dps i can't teach about a third of the course. i can preview PDF and SWF and i working on being able to do so for the 2 kinds of ePUB with mixed results--i'm a artist, not a coder. a staffer on another forum here said content viewer would be back "in a version or two" when is that gonna happen?
