I'm sure. Can you *please* make this prompt optional? It is a source of friction as I close/open the app multiple times throughout the day. When closing the app with launcher (Bunch) this also throws an error which is an additional mouse click.
I think this prompt actually is optional. Check the settings in the general tab. There is a setting which asks how to restore tabs. Selecting never or always will close the app immediately without showing the prompt.
Jonathan is correct you can mark this prompt as optional by heading to Papers > Papers Settings > General > Restore Tabs
