Sparrow Inbox Button
I absolutely love Sparrow and have been using it non stopped since it was in beta as my desktop mail client if you haven't used it check it out:
And they just released a really cool new feature for different inboxes, ie: priority inbox, and unread inbox for gmail, but I wasn't so hot on the placement, so I decided to try out surfacing the button a bit more instead of hiding it.
I also wanted to say AMAZING job on the UI, @Jean-Marc Denis
