Bugs

Usage data shown in the widget is inaccurate. It is only updated after each time I launch the main app. Also, the main app uses fullscreen mode which is totally unnecessary for an app like this and only causes inconvenience. Lastly, theres an obvious bug in the settings tab: The back button disappears when I go back from the "Quota Unit" menu. This disallows me going back to the top menu. Hopefully these will get fixed/reconsidered in future version.
