This project creates a custom toolbar in Microsoft Flight Simulator that allows you to view any PDFs, JPGs and TXT files off your PC. It bundles a very small local web browser by RitaLabs called tinyweb.exe and uses open source ghostscript to convert PDFs to JPG images which MSFS can read. Then just a little HTML to navigate them.
Why? So you can access this stuff in VR of course.
