If you know a way for an app to create files on a system without administrator/permissioned access I think Microsoft would like to hear about it. When testing with crew, one person had UAC enabled in Windows and was unable to save files without launching the program as admin (it did nothing). I'm not a pro; if there's some method I'd need to include to let users save files with their user permission alone, I don't know it. If someone knows it, please let me know; I can add it in an update. As for security, my identity is known, and I'd probably go to jail if I included malicious code. In addition, just because something has open source code does not mean the downloadable binary isn't built with malicious code - so being open source doesn't change much unless you build everything yourself, which most users don't do. I appreciate the concerns though.
