The feature to hide the title bar of Bluebeam Revu (F9) doesn't seem to have any reference points in the menus or a button on the window interface.
If a user accidentally activates this mode and doesn't realize that it was an otherwise unreferenced keyboard shortcut, it's difficult to troubleshoot locally.
The Alt menus don't function and if a user goes into full screen mode (F11) there's still no other menu hints that F9 has a function.
I think it would be valuable to have a button that users can press to restore the title bar of the app within Windows.
Is it possible to request this as a feature?
