Yes, beause it was not so common up until now, I guess. I have thought about what could be the best way of present interactive data when I made a slidify presentation with R. There were a lot of possibilities available but I did not know what would be too much or what would make sense. Also when building a shiny app is the biggest question what does the viewer want to know about the data -- just integrating all sort of options does not make sense in my perception.
