If you open a database in SQLite Database Browser 3.0.2 and the close it via the file menu then the complete structure remains on the "Database Structure" tab, it would be much clearer if this was cleaned up and empty. Also on the "Browse Data" tab the "0 to n of n" remains at the bottom".

This happens every time for me in 3.0.2 on Windows, if you could find time to tidy this up that would be much appreciated. Thanks!
