Thanks for the feedback! Yes, there are keyboard shortcuts (ALT+SHIFT+N for notes, ALT+SHIFT+A for answers).
The guide is still being updated, so the page isn't active yet. There are more details about subscriptions tiers on the checkout page, but I'll update that info to be clearer.
Currently working on the FAQ and footer, so those will be added soon. I appreciate you helping out!
