I'm able to open it, name, and hit save and it looks like it should export to the desktop but I don't seem able to find the file.
I just wanted to confirm that feature was working, I was hoping to write notes and add images to the card then export everything to PDF and maybe save myself writing a report later.
I also must say I love the design and color scheme for this software.
This is like the ideal program, and I really hope you continue to work on it! If you can't find the time perhaps you could consider making it FOSS and letting others continue to build on it? If you start a Pateron to help support this I will gladly join and give a few bucks every month to help with development
