This one does confuse me though. Why not have the sidebar display permanently instead of hiding it within a drop-down? There already appears to be white space and a column header ("More options...") dedicated to it already. Also, why is the button label pi? It's all just really confusing and feels unintuitive. I imagine some thought went into it though, so I'm curious as to the reasoning behind it.
Other than that one particular case, I like what you've done with the rest.
