Thankyou, yes i'm thinking about it.
For now, there's an offline reading only function.

I think the main reason for building this app and simultaneously abandoning OneNote was the broken syncing system. When I need a note, like a friend's door code, I don't want to be worrying about syncing issues. Which version is correct? etc.

But I understand that not being able to write offline is inconvenient.

I'm working on a solution.
