Something that indicates if tag is empty or not while editing multiple files

[tompeto]

When editing multiple file tags at the same time, there would be useful to have something indicating that the tag is not empty. When there are tags with different values in more than 1 file the field in the edit panel appears empty. Something like mp3tag software uses: <keep>, <blank> or a drop down menu to see and choose from the tags written in the files being edited.

I'd use this. At the moment I have lots of columns exposed in the inbox node and computer pane to display the most common offending fields. It would be nice to have an indication in the actual editing dialogue.
