GmailStatus is a Menubar app that notifies you of new emails in your Gmail account.
There’s nothing revolutionary about that, but GmailStatus has some nice features that set it apart from GmailNotifier, even after GmailNotifier has been hacked.
Both allow you to manually or automatically check your Gmail account, jump straight to a Compose window or to the Inbox.
But GmailStatus is smarter about labels. It allows you to see the number of new emails by label and to open them in a browser:
It also has support for a user-defined hotkey and shows you your account usage when you hover the mouse of the menubar icon.
It will work through https and http proxies set in the Network settings.

The latest version released today (1.0.7) fixes a parsing issue caused by changes at Google’s end.
GmailStatus is donation-ware and is available from the developer’s web site
