I'm using calibra 0.8.41 with the latest version of Kindle Collections on a Mac. If I select 'Edit Kindle collections manually...' from the Kindle Collections menu header a new screen is created which allows me to put books into collections. However, I can't use the main calibra screen while this screen is open. It means I can't look up a books tags or metadata.
Was this behaviour intentional or is it a bug?
