The lack of PDF export is a real dealbreaker for me

I'm a teacher, I use freenotes as a whiteboard during my online 1-to-1 lessons. I need to be able to export a single page as pdf. Onenote I can do this in a second. This is a beautiful app, and works very well, but the lack of a pdf export function is going to drive me away. Shame I just paid the lifetime one off fee for it...
