The only thing lacking here is the ability to navigate multiple inbox sections with the keyboard. I use a very similar system (in fact the same, just with different stars) and hitting g + s then using j/k to navigate messages is so much faster than using a mouse/trackpad. It feels sort of barbaric. I suppose this view gives me a nice overview, I just wish there were a hotkey to move from box to box.
