Musicbrainz already stores data in a way that shouldn't be too tricky to display in tables.

It would be great to be able to hit a 'print' button and get a table of your collection to print. Alternatively or additionally, an 'export as CSV' function may be easier or preferable.

Collections seem the most obvious candidate for this function but most page types on MB could also benefit.

I have attached some UI and feature images. They are not to be taken as final, but as examples to get the imagination going
