export option feature request for Shiny app

[devonorourke]

Hi everyone, The Shiny apps are amazing and incredibly helpful to sift through large amounts of information interactively. I can't stress how happy and excited I am to have a chance to use them. Very simple request that perhaps doesn't require much of a change - is there a way to export any of the frames in view by using something other than a "right click + save as" option within the GUI? What I am specifically hoping for is a feature where I can export any of the plots being viewed in the GUI as a .pdf file, rather than the current (and only available) .png option. Thanks again for so many wonderful tools, Devon
