I'm not sure why it was removed, but I used the app to see the temperature in the notification bar. The latest version appears to have this functionality removed. I will uninstall, and look for an app that does what this one used to do. The loss of (or any clear way to turn the temp notification back on) is enough for me to ditch the app, since any common weather app can show the temperature *when it is opened*. Maybe I'll come back later and see if it has been fixed...
