Remember metadata after closing.

[MikeyCarter]

I spend a bunch of time entering meta data for a DVD. But it has an error so I have to eject and clean it. When it's re-inserted I need to re-enter all the meta data again.

Would be nice if it remembered, or at least had the option to export/import.

Just like on excel, when a current work crashed, we have an option to retrieve the unsaved file. Count me in here please.
