There doesn't seem to be any to view or scroll the entire tag values from the original tags when they are longer than the display area.  For the new tags, you can at least click in them to edit and move around the "new" tag values, but you can't do the same in the old tags.  I have lots of files (especially classical) where the tags are very long, and there's nothing within the view to differentiate between files.

This is a request to add some way to either manually or automatically scroll the tag display for better handling of very long tags.  It would be nice to have that on the new tags too, so you can see the end of all the longer tags at the same time.

It would also be nice to have a way to condense the tag display to highlight the portions of tags that are different between files.

Also, the filename display at the bottom of the window has the same problem, you can't see the end of the filename.  This is especially a problem when you can't even see any of the filename, only the beginning of the path.
