Hi there!
Not really a big issue but: I can't close the app initially if any document is open.
Here is how to reproduce it:
Create a document of any kind and populate it with some elements.
Save the document.
Then change something.
Finally try to close the app by using the upper right X.
APub then prompts the question wether or not you want to save the changes.
But irrespective of you answer the app does not close (after having saved the changes).
Is it intended or a small bug?
Best,
Volker
