Extension fail

While this could be a nice app for Mavericks (residing in the top bar…), I bought it mainly for the Extensions feature.
That’s exactly the point: once you quit the app, the information that needs to be displayed in the Notifications sidebar disappears as well.
You need to start the app in order to have the information available in the sidebar…
