Notes has a feature called "Lock Display" or "Lockout" (press F5 or choose File - Security - Lock Display).
Do you use it? How often?
Do your business end users even know it exists?
We are considering not having that feature in Hannover. If we dropped support of this feature in Hannover would it adversely affect your decision to purchase or deploy it?
We're considering dropping it because Hannover allows for several different window management models-- in addition to having each document open in a tab contained in a main window, you can set a preference to have all documents open in a new window. In such a case, implementing the screen lock feature to apply to all these windows would require more work. It's doable-- but would you rather have us working on new mail, calendar or contacts features?
