Thanks! I'll get on the keyboard shortcuts and title text now. I'm not sure why it would be slow since nginx is caching all of the demo pages.
About the inbox thing: I wasn't sure what the best phrasing for that would be, but the idea is that you can use the X and the Q buttons to process all of the items quickly so that your "inbox" (the items you haven't seen) stays at zero, even if your Queue (what you haven't read) has things in it.
