I'm still trying to fine the right PDF setup for my Surface Pro. I scan everything in that I receive so have a huge library of PDFs, and transitioning over from Mac. I have tried a half dozen or so PDF apps and Drawboard is by far the best experience with a pen. I pulled the trigger on buying it a bit to quick, and then set it as my default PDF app. Now I know longer get PDF previews in Explorer. If I change default back to Foxit or Nuance, the previews come back. Is there a way to use Drawboard for opening a PDF, and something else for preview?
