Nice! It works - the ink pastes fine into OneNote and OneNote immediately can search the ink (at least where my writing was legible!). Same with Windows Journal, which converts it to text, too.

I see that merely changing the "Page" in your app copies that page to the clipboard, which makes it a bit easier to paste page after page into OneNote/Journal.

Seems like you can only have one PDF in the same directory as the EXE. A File | Open op would be convenient...
