I’m with Daniel on this one I think. Spawning out to an external reader for handling PDFs gets the job done, but it’s not really elegant.
It can certainly be argued that aspects of Roon’s UI have rough edges, with unfinished features. The PDF reader, the “Now Playing” screen (which has not yet acquired proper “screensaver” functionality) and Internet Radio are prime examples of this.
We know that the Roonies continue to work on the UI experience (e.g. Brian has just posted that a major update of Internet Radio is in the works), so I’m hopeful that the PDF experience will be improved. But in the meantime, I can live with it. It certainly isn’t a dealbreaker.
