I had some suggestions so here i go:
Add/remove (custom) records: many people have different ways of storing there information. I personnally miss a location number, all my movies have a specific number so they can easely be found.
Add a Smartlist: itunes style

Mass add files in folder and subfolder.
Mass edit files, why? because sometimes when you import a DB from someone else then you would want to make all those files belong to the owner so that they won't get mixed up. the progam the godfather (a MP3 tag/renamer ) has got these great capabilities.
that's what i miss

keep it up.
