Trojita supports saving and restoring the "state" of the application upon exit. This means that once user has resized the window or some control item to a particular dimension, hid some UI item or configured a view to always show all columns, these settings will persist and will be restored upon next start of the application. Unfortunately, the state of the "show main menu bar" is not part of these settings, and it's your job to fix this.

See the Trojita's home page for contact information.
