If you are logged in to Konami's official database, the "Export Master Duel/Neuron" button on YGOPRODECK deck pages will automatically fill out a new deck in the official database for you to edit and save. You no longer need to first click an export button on YGOPRODECK, open the official database, create a new deck in the official database, and then click an import button.
Full Changelog: 1.1.0...1.2.0
