[Feature Request] Tag Editor Improvement

[ghost]

Actual behaviour

• Opening the tag editor for a file with no previously added tags doesn't show the name of the file so you have to remember the artist and title of a song before opening its tag editor.

Expected behaviour

• The filename should be listed somewhere in the tag editor so we can copy the information to the right tags (for example if the file is a download from Youtube and has a artist - songtitle format)

Steps to reproduce

1. Open tag editor of a file with no previously added tags.
