Hi to all,
I was working with my ebook calibre library and thought of a feature that would be perhaps useful to a user.
When user selects any given number of books, right-clicks for the 'Remove files of a specific format from selected books..', a list pops-up so that user may choose the file format. It would be useful to be able to see next to each format type the actual number of books having this specific format.
For example, mobi (30), lit (10), epub (20).

Just a suggestion and an idea for an otherwise excellent product.
Best regards to all
Kater
