What settings can be set there?
All entries listed here should go to the [general] section except where indicated otherwise.

Default is 1 (true). Set to 0 if you don't want the Strong numbers to appear in popups, no matter if the current/active Bible view displays them.
popup.morph=0
Default is 1 (true). Set to 0 if you don't want the morphological codes numbers to appear in popups, no matter if the current/active Bible view displays them.
