Unfortunately I am not a Windows programmer. But Quiver uses a simple JSON format for notebooks and notes, as documented here: https://github.com/HappenApps/Quiver/wiki/Quiver-Data-Format https://github.com/HappenApps/Quiver/wiki/Quiver-Data-Format So anyone with the right skills can take Quiver's design and format, and make a similar app for Windows. I wouldn't mind at all.
