Preferences : open and return to last sub-window opened

Hi, since, at the moment, it's very user unfriendly to use, for ex., the Protect Library feature in Preferences (very often, i.e. every 5 minutes) because to go there the path is long and, in addition, when we return to it we don't land in the same sub-window we were last time. It'd be handy, for ex. to land again in the Protect Library sub-window as I go there back and forth every 4 minutes to switch in on and off as I edit my library.

Thank you for your consideration, I think it'll be useful to all users.
