I don't support Google-only authentication. I strongly recommend providing more options such as OpenID, Twitter, and email-based.
Sometimes select command note (backspace) doesn't work bc it will trigger the browser's Previous page so cant delete a txt row. And Ctrl-U for file upload triggers Inspect Element so sometimes using buttons is needed, I don't know when it does this exactly, seems random.
Fantastic. I've been looking for a clean, notes app with easily condensible bullets, for forever. Sure it's highly subjective but Schema has native support for the way I love to take notes: beginning with a condensed outline and expanding on topics that I have a lot to say about. I love that the note taking window is clean and empty.
My cons are wishlist features, and I'll caveat by saying I approach this as a worker, not a student. My thoughts are based on Schema as a note taking tool, not as an educational content or lesson delivery product.
