I've experimented in the past with putting a node at the top left to say to people "Scroll down", or "Scroll right", depending on which layout I've used, but folks giving usability feedback who are experienced with it say that it's annoying and irritating constantly to be told something they know. So it's the usual problem of helping the novices versus annoying the experienced. Given that there's no login or other persistence I'm pretty sure I can't solve that. I'll probably put the top-left node back in. Thanks for the feedback.
