I Synced Settings in InDesign CC, then opened InDesign CC 2014, and Synced again. Then came this 'Ready to apply' message, without an Apply-button (this can be done only in a document window…?)
Ok, I had to create a document first to Apply the setting for the application.
And after applying, my New Document-dialog does still not reflect my old settings.
This could be so much easier…
