It would be nice to have "Start with open windows from last session".
I mean, when you shut down newspro with 3 or more open windows, Newspro would reopen this windows on startup, including the used filters in these windows.
With large groups this might slowdown the start-up procedure, but reopening, recloning and re-filtering will take probably even more time.
And if it is configurable in a way that you can shudown with, or without remembering the last windowconfig it's up to the user to use or not use the option.
