Previous button - to the previous slide in the sequence of slides or the last slide visited?

Thanks, Maria. I just wanted to be sure I wasn't missing something. 

And, yes, the current functionality is similar to a browser back button....but training isn't the same as browsing. We organize our courses to move through material in a logical sequence that best suits the material and builds the learner's thinking, so having an option for last viewed or previous screen in the sequence would be a real time saver over manually adding a trigger to each screen.

If anyone else reading this would like this choice, perhaps you could chime in. I imagine one consideration for what makes it to the feature roadmap is community requests.

Thanks for your help, Maria!
