This is awesome!! I would like this to be my portal to the web. My current portal to the web is my browser, but it doesn’t allow me to create notes/cards/recalls on youtube videos I watch or on articles I read. I think it would be good if the main content appears on the center (I see pdfs showing on the right side of the screen).
